--- Comment #32 from paulo i30817@gmail.com 2011-07-15 01:34:01 CDT --- Ok the cause has been found (a stack mishandling corrupted the ESP register) and the fixpack will be corrected eventually in the next minor version (i'd expect soon).
So as it is a fixpack bug and unless you want to figure out why it is crashing with wine but not with windows, or why wine compiled with O2 crashes but not O1, i'd guess this can be closed.
