mysql-5.0.77-4.el5_4.1 on RHEL 5.4
At some point, mysqld died. When i try to restart, mysqld.log says:
;InnoDB: End of

InnoDB: corruption. If this happens in an InnoDB database recovery, see

InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to

InnoDB: about forcing recovery.

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=0
read_buffer_size=131072
max_used_connections=0
max_connections=100
threads_connected=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections
= 217599 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
thd=(nil)
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 is NULL, did you compile with
-fomit-frame-pointer? Aborting backtrace!
The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html
contains
information that should help you find out what is causing the crash.
100104 16:31:15 mysqld ended
Trying innodb_force_recovery = 4 did not help. Googling isn't really
helping me. I don't know what I can do about a "stray pointer".
