OK.  Can you try a session that only loads libgnutls, but doesn't load
image libraries?  I think "emacs -nw" should achieve that, if you then
use whatever features that load GnuTLS.  The question is, if libgnutls
is the only DLL loaded, does Emacs still crash at exit, with and
without my unloading patch?

Thanks.
