When GC starts taking a long time, I can easily type C-g C-g during a
GC if I have garbage-collection-messages set.  This stops Emacs as it
should.  When I continue it, it asks (correctly) if I want to abort
and dump core.  I say no, and then it crashes.

A backtrace showed me why: tty_send_additional_strings calls
Fterminal_parameter which calls Fassq which does QUIT;
