Thank you for the bug report.

This also happens on Linux 4.1.8 latest Bk source:

miguel@hegel:~/dbs/4.1$ libexec/mysqld
041214 17:56:37 InnoDB: Started; log sequence number 0 43634
libexec/mysqld: ready for connections.
Version: '4.1.8-debug' socket: '/tmp/mysql.sock' port: 3306 Source distribution
mysqld: item.cc:554: virtual longlong Item_field::val_int(): Assertion `fixed == 1' failed.
mysqld got signal 6;
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=1073741824
read_buffer_size=67104768
max_used_connections=1
max_connections=500
threads_connected=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 1308702 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...

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
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort...

The manual page at http://www.mysql.com/doc/en/Crashing.html contains
information that should help you find out what is causing the crash.
