For targets mingw/cygwin this symbol allocates and probes stack (see /gcc/config/i386/cygwin.asm). The VC variant export the same symbol name in kernel32, ntdll, and ntoskernl. But the MS variant just probes the stack and does not allocates stack space. I temporary removed the exports from our .def files in mingw-w64 and this solves the issue so far. The bad side of this fix is, that libraries generated by VC can't be linked proper, if they reference the ms __chkstk variant. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39356
