Still occurring in the 4.1.21 release build, in "pro-gpl" on Solaris 10 (x86).

In 4.1.21, I found an even weirder value -
could there be an un-initialized variable or a race condition involved ?

I would like to have it verified that this is really a problem with a 5.0 or 5.1 server, since 4.1 is under conditional support.

This is not repeatable in newer version of MySQL (5.0, 5.1).
