Hallo Waldemar,

Please keep questions on the list because others may be interested in
this issue too.

BTW, from my original posting:

There is no threading in Cygwin Perl.

Unfortunately this doesn't work (yet?).  If you are a threads expert
please help to debug why we cannot build Perl with threading.

Gerrit,

I suspect either Robert Collins or Thomas Pfaff could answer your
question, as they appear to be the resident threads experts.  Perhaps
they can suggest a way or improve the cygwin dll in a way which would
support a threaded perl.

Cheers,
Nicholas

This seems to be a problem with a threaded perl and fork, the child
crashes with a corrupted stack.
It is rather difficult to track it down as long as gdb does not support a
follow-child mode. I will investigate a bit further.
