You are not supposed to continue using Emacs as usual after it
recovered from a C stack overflow. You are supposed to exit Emacs and
restart the session.
The C stack overflow recovery is provided to allow you to save your
edits instead of losing them.
P.S. I was somehow certain that we say the above somewhere in the
docs, but I cannot find it, so maybe I was dreaming. Patches to add
that are welcome.
