Created an attachment (id=22504) --> (http://bugs.winehq.org/attachment.cgi?id=22504) Crash log
Tracking down a wine crash in running a .bat file from cmd, i narrowed down the issue to a simple command line:
Z:\home\mig>IF DEFINED FOO ()
works (of course it does nothing)
Z:\home\mig>IF NOT DEFINED FOO ()
crashes:
wine: Unhandled page fault on read access to 0x00000000 at address 0x7ed18893 (thread 0028), starting debugger... ...
... Traces attached as separate file ...
The problem appears using wine-1.0.1 but it was also there in win-1.0

This fixes it for me, I'll send it in. Would you mind testing it to make sure it doesn't break anything else?

I think this one's better. Would you mind checking it doesn't break your batch programs in other places?
