You never mentioned -gtoggle before.  It seems you are using
--with-build-config=bootstrap-debug, correct?  If you report a problem,
*please* provide *all* the necessary information about your build, which
includes exact configure options used.

Instead of retrying with each and every gcc release, it's much more
useful to stay with a single one that fails and investigate that in
detail.  Unfortunately, you never provided the exact command lines used
to build the differing stage2 and 3 object files I've requested some
time ago.  This way, the difference would have been immediately
obvious instead of running in circles for weeks.
