The crash is caused by incomplete FlsFree implementation. There's a

Really? Are you sure that's it?
Yes. If you need a workaround to run you app you can comment FlsAlloc
export. If this function is not available msvcrt will use TlsAlloc. I've
also confirmed it by adding a hacky implementation of zeroing the memory
on free.
By the way, to aid my future Wine sleuthing, can you share any hints
on how you figured this out?
There's no easy answer to this question. I've looked on the relay log
and after figuring out it may be related to Fls* functions I have added
some more traces to it. Afterwards it was quite obvious that application
was using a value that was supposed to be no longer valid (FlsGetValue
was returning old pointer instead of NULL).
OK. Do you know if it is acceptable form to post a windows binary as
an example case on the bug? The DLL part of the bug has to be a
windows binary.
I think it's ok if it's your code and compiler license is allowing to
publish produced executable. I've already seen some executables attached
to bugs.
