Bug 5466

если запустить команду mysqldump с ключем '--opt' ,  
то mysqld однозначно вываливается при попытке вычитать первую попавшуюся 
таблицу типа InnoDB . 

Actual Results:  
# cat /var/adm/mysql/info

InnoDB: http://www.innodb.com/ibman.php about forcing recovery. 
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. 
 
key_buffer_size=8388600 
read_buffer_size=131072 
max_used_connections=0 
max_connections=100 
threads_connected=1 
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 
225791 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... 
frame pointer (ebp) is NULL, did you compile with 
-fomit-frame-pointer? Aborting backtrace! 
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.
