--- Comment #14 from paulo i30817@gmail.com 2010-09-04 21:44:48 CDT --- knights of the chalice does not crash anymore in x86-64 with this problem. There are other non-fatal errors, but it seems to work.
But as i don't know what causes the game to choose this function in the x86-64 environment (it didn't crash in x86) and i changed my drivers, i can't really confirm.
