Apart from that I set the default stack size to 1 Megs.

Thanks for your testcase, btw.

It helped me a lot to understand how Windows handles the stack and the
stack guard pages.  With its help I also found two long-standing
problems in glob().  When I added the glob implementation from FreeBSD,
I made some innocent changes which turned out to waste a lot of stack
space.  And, at the time we had no locale support so I removed it from
the code, so I took the opportunity to add locale support back into the
code.

I'm still testing one of my changes before checking in, but I'm almost
GTG.
