Description:
Seeing this crash in the mysql-5.1.23-maria-alpha-pb297 build when running my application testsuite.

I used engine=myisam, so it's not a Maria bug.

ntdll.dll!RtlCheckForOrphanedCriticalSections()
mysqld.exe!my_rw_wrlock
mysqld.exe!query_cache_insert
mysqld.exe!net_real_write
mysqld.exe!net_flush
mysqld.exe!net_send_eof
mysqld.exe!net_end_statement
mysqld.exe!dispatch_command
mysqld.exe!do_command
mysqld.exe!handle_one_connection
mysqld.exe!pthread_start
mysqld.exe!_callthreadstart

How to repeat:
will upload a standalone testcase later.

It seems very likely I had just missed the updates made in bug #30887 . I will retest and if no crash happens, this I close this bug.
