Description:
After working around Bug #8646, I inserted a long dump consisting of one CREATE TABLE and some 250 one-megabyte multi-row INSERT statements. If I remember correctly, I shut down the database cleanly by sending SIGQUIT to the mysqld process. Also, InnoDB doesn't display any crash recovery messages. However, mysqld refuses to start:

/home/marko/mysql-5.0/sql/mysqld: Out of memory at line 195, 'my_alloc.c'
/home/marko/mysql-5.0/sql/mysqld: needed -56 byte (0k), memory in use: 2151689 bytes (2102k)
050221 21:23:44 [ERROR] Crash recovery failed. Either correct the problem (if it's, for example, out of memory error) and restart, or delete (or rename) binary log and start mysqld with --tc-heuristic-recover={commit|rollback}
050221 21:23:44 [ERROR] Can't init tc log
050221 21:23:44 [ERROR] Aborting

How to repeat:
I don't know. Maybe create a big enough transaction, and then restart mysqld.

Suggested fix:
Make it possible to essentially disable XA at runtime if you cannot figure out the cause of this bug by the 5.0.3 deadline. I tried both suggested values of --tc-heuristic-recover, but the database refused to start up.
