thanks for the testcase, but I'm not sure yet this is really a bug in
Cygwin.  Your bug report is missing a bit of info.  Is that Windows 8 or
8.1?  32 or 64 bit?  If 64 bit, native or in 32 bit mode?  Which Cygwin
version are you running?

Personally I tried your testcase on Windows 8.1, 64 bit, with 64 bit
Cygwin, 1.7.33 as well as current CVS HEAD, and your testcase works
fine for me, even when running from a pthread.
