I'm using 24.3.2 with Ken's cygwin patches.

The STC is:
1. gcc -g -ostc -xc <(echo "int main() { return 0; }")
2. Fire up emacs M-x gdb and point it at stc
3. b main
4. comm 1

If it's fixed in later versions, though, maybe Ken's (hopefully 
soon-arriving) cygwin package update that fixes the stack overflow 
problem will also pick up this fix.
