Description : SELECT MONTH() or YEAR() causes server to crash How-To-Repeat :

I had a (myisam) table with one text field that contained a load of (alledgedly) dates, but the data wasn't perfect, so there were lots of 2000-11- and -12-01 kinds of things. doing SELECT MONTH(dirtyfield) or YEAR(dirtyfield) resulted in a server crash on WinNT (stack traces attached), and some odd behaviour on Solaris. On the sun, the server disconnected all connected users, reset it's uptime to 0 (but didn't go down), and got confused about access permissions; allowing users to connect to the server, but not to use any of the databases. FLUSH PRIVILEGES corrected the behaviour.

Cheers,

Max
