--- Comment #7 from Daniel Santos daniel.santos@pobox.com 2010-05-17 03:03:32 --- Created an attachment (id=28032) --> (http://bugs.winehq.org/attachment.cgi?id=28032) output of debug session
Here's the output from a debug session where I ran the app until I got a 1st chance exception, I didn't bother passing it because it looked fatal, it would appear the the variable "thunk" is zero (I presume that's what EAX is storing on this frame).
I hope this helps.
