Hi Vladimir,
On a hunch I backed out r253656. That let the Ada and Go bootstrap
complete. It looks like your fix for bug 82353 is triggering this
ICE.

I've been running into the following errors during the bootstrap
of the top of trunk on x86_64 with no local changes. They don't
seem to be triggered by other front ends. Before I open a new
bug, has anyone else noticed them and maybe already filed one?
(I don't see anything recent in Bugzilla but I could be looking
for the wrong thing.)
Thanks
Martin
