panic: MySQL tables currupt and can't reload

Hello all.

If there are any expects here on mySQL I could use some help.

I have a database that reports two tables corrupt when running mysqlcheck.

mysql dies if one of a command attempts to write to those tables, though
reads are fine (and I have done appropriate dumps of the data).

However, if I try to do a reload (or even try to drop the database
before recreating) I get mysql crashing.
Below is a past of the messages I get when it crashes.

I am not a C++ programmer so the stack trace will likely not be of much
help to me.

Any suggestions are welcomed -- including the best way to nuke the whole
database and start over. There is only one database in use and it's
backed up OK.

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
= 233983 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=0x447f4fd0, backtrace may not be correct.
Stack range sanity check OK, backtrace follows:
(nil)
New value of fp=0x2424b40 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
