Description:
Version: '5.1.23-beta-debug' socket: '/tmp/mysql.sock' port: 3306 yes
mysqld: field.cc:6288: virtual int Field_str::store(double): Assertion `local_char_length < 5 || length <= local_char_length+1' failed.
070923 4:01:12 - mysqld got signal 6;
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.
key_buffer_size=8388572
read_buffer_size=131072
max_used_connections=2
max_threads=151
threads_connected=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 33215 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=0x42895a54, 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/refman/5.1/en/resolve-stack-dump.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.

thd->query at 0x8de9030 = insert into t1(col000) select (rand(`t1`.`col001`)) from t1 where col000 <> (convert(`t1`.`col001` using latin1)) limit 1
thd->thread_id=2
How to repeat:
use debug build of mysqld and run this:
some testcase
-----------
drop table if exists t1;
create table `t1` (`col000` char(10) not null,`col001` smallint not null)engine=innodb;
insert into t1 values (),(),();
insert into t1(col000) select (rand(1)) from t1 where col000 <> (convert(`t1`.`col001` using latin1)) limit 1;
another testcase
----------------
drop table if exists t;
create table t (a char(10),b int)engine=innodb;
insert into t values (),(),();
insert into t(a) select rand() from t;
