[Gc] Windows crash

I'm using GC 6.5, compiled to a windows DLL using cygwin gcc with the 
-mno-cygwin flag.

I have a relatively simple program that uses GC to allocate a few 
objects and strings while responding to GUI events, and which calls 
GC_collect_a_little after processing each event until either PeekMessage 
returns true, or GC_collect_a_little returns false.

If I enable incremental collection, I occasionally get an exception 
C0000096 (Illegal Instruction in non-priveleged mode) while executing 
code inside NTDLL.DLL.
