Comment 2 for bug 939248

we got a similar crash, the printed information is a little different. we are using Percona Server 5.5.18

130401 23:27:45 InnoDB: Assertion failure in thread 1348516160 in file btr0pcur.c line 414
InnoDB: Failing assertion: page_is_comp(next_page) == page_is_comp(page)
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

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=104857600
read_buffer_size=1048576
max_used_connections=526
max_threads=2100
thread_count=233
connection_count=233
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 3118475 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...
