I just built the 4.1.12 release from the source RPM to update our DB server running 4.1.11 (also built from the source RPM).  Upon running a "rpm -Uvh" for the server package, I get the following error message:

050516 10:29:00  InnoDB: Started; log sequence number 0 43654
mysqld: ready for connections.
Version: '4.1.12-standard-log'  socket: '/var/lib/mysql/mysql.sock'  port: 3306  MySQL Community Edition - Standard (GPL)
mysqld got signal 11;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 352176 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
Cannot determine thread, fp=0xbe7fea08, backtrace may not be correct.
Stack range sanity check OK, backtrace follows:
New value of fp=(nil) failed sanity check, terminating stack trace!
Please read http://dev.mysql.com/doc/mysql/en/Using_stack_trace.html and follow instructions on how to resolve the stack trace. Resolved
stack trace is much more helpful in diagnosing the problem, so please do
resolve it
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort...

The manual page at http://www.mysql.com/doc/en/Crashing.html contains
information that should help you find out what is causing the crash.

I ran "myisamchk --silent --force */*.MYI" to ensure that all index files are in order - no problems there.  Resolving the symbols in the above error message, with the command "resolve_stack_dump -s mysqld.sym -n mysql.stack" provides the following information:

I've reverted back to 4.1.11 for now, which seems to be working just fine.

How to repeat:
Build and install MySQL 4.1.11 from source RPM (client, server and devel packages) on Fedora Core 3 (with all system updates applied).  Started MySQL (service mysql start).  Build 4.1.12 release from source RPM and upgrade client, server and devel packages.

Confirmed this exact same problem on FC2 as well.

Also, same problem on 4.1.12 binaries as well as source.

Same occurs on SuSe 9.2 Professional

If you have installed the RPM package 4.1.12 (which had problems)
please test with the today package 4.1.12-1.

Thanks in advance.

I've installed 4.1.12-1 in our staging environment and it looks like it's running well.  Thanks for the quick fix on this. I'll keep an eye on things over the next few days just to be sure everything's cool, but at this point, it looks like we're in good shape.
