Hmm, I have an earlier version on my Windows 7 machines.  This one
seems to come with some security update.  But it's still legit, I
think.

At this point, I think the only practical way forward is to run Emacs
under GDB and show the backtrace from the crash.  Which versions of
GDB do you have on that system?  (Run "gdb --config" to see the
answer.)
