You can't and needn't link with -lpthread. Wine has its own
pthread implmentation.

I tried your included code and it works just fine unless you
link with -lpthread, then it crashes in the same way as in your
attached picture. But then you should never link Wine with
-lpthread so that is not really a bug.

Of course Wine pthread implementation it not in any way complete
so some function might be missing and some might only be only
partially implemented and of course some might be incorrectly
implemented.

So please try again without linking with -lpthread.
