Description:
The mysql server crashes while updating a table row within a stored procedure called multiple times. Don't know why ...
see How to repeat section
...
it also crashes when i add the user_id as parameter to the procedure and call:
do_opt_in(161); /* works fine */
do_opt_in(162); /* crashes */
I have tested it on 2 different Linux machines and also with the mysql 5 developer branch (5.0.3-beta dev) from today.
The Trace ...:
Version: '5.0.2-alpha-standard' socket: '/var/lib/mysql/mysql.sock' port: 3306 Official MySQL-standard binary
pure virtual method called
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=16777216
read_buffer_size=131072
max_used_connections=2
max_connections=100
threads_connected=2
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 80383 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...

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
