the gcc or glibc unwinding is in use, not wine's if I take it correctly from
the bakctrace.

actually it is built with it and crashes.
Atfer i change thread.o with -fno-asynchronous-unwind-tables
it starts to work again.
so somehting in there confuses the

Which glibc are you using?

It sounds like this bug
http://sourceware.org/bugzilla/show_bug.cgi?id=3597
But your glibc should be OK.

i can reproduce this.
I will try to bisect which file of wine gets miscompiled to get a smaller
testcase.

--- Comment #6 from marcus at jet dot franken.de 2010-11-25 10:01:26 UTC ---
first wine search converged on ntdll.dll.so being miscompiled (as i expected to
some degree).
i will tomorrow focus on the specific object files.

.o hunting converged on dlls/ntdll/thread.o
however:

--- Comment #8 from marcus at jet dot franken.de 2010-11-26 07:31:39 UTC ---
when I add
-fno-omit-frame-pointer -fno-asynchronous-unwind-tables
it goes back to the good behaviour.
