Description:
101016 13:11:21  InnoDB: Assertion failure in thread 2136176960 in file row/row0mysql.c line 3373
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: http://dev.mysql.com/doc/refman/5.1/en/forcing-recovery.html
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=16777216
read_buffer_size=1048576
max_used_connections=3624
max_threads=5000
threads_connected=10
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 15429352 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

terribly wrong...

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains

How to repeat:
row/row0mysql.c line 3373 is "ut_error" in the code below in row_drop_table_for_mysql
        default:
                /* No other possible error returns */
                ut_error;
        }

Note that InnoDB crashes here without logging an error message. It would be nice to know the value of "err" here that is not handled in the switch statement. All calls to ut_error must be preceded by logging an error message if we are to debug it.

Well, I was able to get it to crash on the DROP TABLE innodb_table_monitor this morning.  (I was actually just cleaning up my instance to re-test today, tried dropping the table to start from fresh, and it crashed, first statement.)

Here is the error log, so perhaps it contains some additional, useful information:
