When custom app (linked with libmysqlclient) opens a connection, and that connection times out (after several hours of no traffic) a subsequent mysql_ping will crash the app.

"res_config_mysql.so" is the name of the mysql module in my app. IP addresses and passwords have been changed to protect the innocent.

How to repeat:
Amazingly, this is very repeatable. I've repeated this crash every morning so far.

Open a connection with mysql_real_connect().
Wait about 5 hours (I'm not sure of the exact time frame, but I know that 3 hours isn't enough and that overnight is plenty).
Call mysql_ping() on the 5+ hr connection.

Suggested fix:
My cheezy-i'm-not-a-C-guru-programmer fix would be to add a check in my_strcasecmp_8bit to see if "s" is valid before I run any comparisons on it. However, I'm sure that it should never reach this state so I'm guessing there is a better solution.

Testing on Slackware 10.0 with a sleep connection through 6 hours and
an mysql_ping() performed, the client application not crashed. Could
you please attach your my.cnf file ?

Thanks in advance.

This morning when I attempted to repeat this bug, I was presented with a new error:

Server Error: Can't initialize character set latin1 (path: /usr/share/mysql/charsets/)

The latin1 file has global read permissions as does the path to it.

I am using unixODBC 2.2.11, MyODBC 3.51.11 and MySQL 4.1.11. 
ODBC function SQLConnect returns the following error when called multiple times (about 20 times) in a C program:
#Character set 'latin1' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index.xml' file

Sometimes my program seg faults in function my_strcasecmp_8bit in libmysqlclient_r.so library.
[26 Apr 2005 19:08] Saju Paul
Workaround: (if you are not interested in the latin1 charset)
edit /usr/share/mysql/charset/Index.xml. Delete all lines defined for latin1.

Now I'm getting this on a brand new app I just created. What is the deal? What do you guys need to help fix this? This is obviously a bug.

argh. I can't continue developing my app cause everytime I load the mysql module the app crashes.

let me know what you need. I'll send anything.

This apparently looks like a memory corruption.
The crash occurs when corrupted data are accessed, and it does not tell us much.
Try to find when this corruption happens (this is not easy :(, you can use e.g. valgrind, or watchpoints in gdb)

I wrote a simple test program that uses unixODBC 2.2.11 to connect to a MySQL 4.1.12 database with MyODBC 3.51.11 connector.  The program runs on linux Mandrake 10.1 with 2.4.27 kernel. unixODBC, MySQL and MyODBC have been compiled from tarballs with gcc 3.4.1.
The program launches 10 threads, each thread creates 6 connections to the database and close them. If you allocate the SQLHENV in the main program and use it in each thread in order to allocate each SQLHDBC, everything is OK. Now if you allocate a new SQLHENV in each thread, ODBC reports the following error when creating the 5-6 last connections:

Character set 'latin1' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index.xml' file
(1) HYT00:2019:[unixODBC][MySQL][ODBC 3.51 Driver]Can't initialize character set latin1 (path: /usr/share/mysql/charsets/)
Sometimes the program seg faults.

I also tested the same program with a PostgreSQL database, it works fine. So unixODBC does not seem to be the problem.

here is the test program (the program is linked with tls pthread library)
to compile it:  gcc test.c -o test -lodbc -lpthread
Hope it helps.

This bug is also blocking me from implementing a commercial server using MySQL.  Using C++ with unixODBC 2.2.11, MySQL Server 4.1.14 and MyODBC 3.51.10 on SuSE linux 9.0.  It happens every time if I make a connection, then disconnect, then make a connection again.  Each time through the connection process, I'm allocating a new ENV handle, new connection handles, etc.

Valgrind says my_strcasecmp_8bit is reading memory that was freed during SQLDisconnect:

This bug report contains information about 3 (different) problems, reported by Matthew Boehm, Philippe Jalaber, and Mike. I am closing it as "No feedback" (because there is no feedback from the original bug reporter for a long time).

I also think they have nothing to do with server itself, but are related to the ODBC driver.

Philippe and Mike: please, open new bug reports, if you still have the same problems with MySQL 4.1.14 and MyODBC 3.51.11.

1. We have actually two instances of mysql 5.0.20 on two different machines connected via mysql replication, so application connects to both instances BUT, this is really does not matter same machine or not same machine.

Machine     1       Machine     2          
MySQL       1  <->  MySQL       2       
Application 1       Application 2  

Application 1 connected to both MySQL1 and MySQL2       
Application 2 connected to both MySQL1 and MySQL2

However, again, let's look at this model in simpler context - we have MyODBC client, DON'T linked with server, always connecting to the server via tcp/ip .odbc.ini attached.

we are NOT using libmysqlclient.so.14, since the protocol has been changed and therefore libmysqlclient.so.14 can not be used to connect to MySQL 5.0.xx - as you can see

/usr/local/lib/libmysqlclient.so.14 is symbolic link to /usr/local/lib/libmysqlclient_r.so 

and /usr/local/lib/libmysqlclient_r.so is really libmysqlclient_r.so.15.0.0

nm /usr/local/lib/libmysqlclient_r.so | grep FILE | grep libmysqlclient_r [1] | 0 | 0 | FILE | LOCL | 0 | ABS | .libs/libmysqlclient_r.so.15.0.0

This symbolic link has been created to fake perl DBI.

In addition to that, /usr/local/lib/libmyodbc3-3.51.12.so is not linked with /usr/local/lib/libmysqlclient_r.so at all ...

I think it's linked statically.

3. I have sent pmap - map of the process in memory - you can see that only libmyodbc3-3.51.12.so really used there and libmysqlclient_r has not been used. I guess that libmyodbc3-3.51.12.so is statically linked.

4. Unless you have certain problem clarification, with an appropriate test cases, that will show what is the problem and how will it be solved by upgrade, I am NOT going to upgrade working customer production - it's critical 24x7 production - HLR proxy of tier 2 cellular operator environment.

OK. Are you sure it is MySQL 5.0.20 that is used on that another machine, where MyODBC is installed? I already know from your next email that it is 32-bit. But according to other your results I am not sure about 5.0.20. What exact MySQL binaries did you install on that client machine?

> 2. my.cnf attached

Thank you. Is it from that another machine, where MyODBC is installed? If no, please,  send one (if any) from it. Just for completeness.

According to the following, these results are from the same mahcine where your application works. Great. But(!) note that you have *.so.14 is used. It is from MySQL 4.0.x days! And it may surely not work properly with character sets, I think. You need libmysqlclient.so.15.

Yes, we clearly see that version 3.51.12 is used, and:

it seems it is not linked with libmysqlclient.so.* at all (or I missed something).

Let me list all the directries one per row:


So, before /usr/local/lib (where libmysqlclient.so.14 is located) you have:


I do not think these directories are still needed in LD_LIBRARY_PATH at all (although it is not a problem for this issue).

The test case below (actually the same program listed as the comment) works well if use thread-safe driver binary (libmyodbc3_r-3.51.12.so) instead of non-thread-safe one (libmyodbc3-3.51.12.so). As non-thread-safe version will be eliminated from the distribution I would recommend using the thread-safe versions of MyODBC driver in non-multithread applications.

One more note regarding this bug report: all MyODBC drivers are being linked statically against libmysqlclient.a/libmysqlclient_r.a libs. So, "ldd libmyodbc3-3.51.12.so" will not show any dependences on mysql client library.
