INNODB_SYS_INDEXES crashes server

[Baron Schwartz]

This may be the same thing as bug #627189, but I'm not sure. If necessary I can probably get a machine with a snapshot of the data and the same build of MySQL. This is for Percona customer issue 14209, running on Gentoo.

mysql> select * from INNODB_SYS_INDEXES;
110509 10:12:05 - 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=205520896
read_buffer_size=1048576
max_used_connections=45
max_threads=120
threads_connected=11
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 570646 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...
