I suspect that you were simply trying to provide an element of 64-bit
readiness, without any consideration of whether, or not, the original
32-bit implementation actually worked; consequently, you've adapted
broken 32-bit code, to create an equally broken 64-bit derivative.

Admittedly, I might have done the same, if I hadn't searched the bug
tracker, for any potentially related issue, and reviewed those which I
found; in particular, the one I mentioned earlier in the thread, which
was, erroneously IMO, closed as invalid.

The good news is that it may not be as difficult to fix as I had first
thought; indeed, I have a working adaptation which may resolve one of
my own FIXMEs, (in mingwex/glob.c), so it's likely worth pursuing.  I
do have one reservation: the current __try1(exception_handler)
followed by free-standing __except1 semantics seems rather
back-to-front to me.  Surely, __try2 { action code }
__except2(handler) { remedial code } seems more logical?
