Why should we consider this an Emacs bug?  Is there any evidence that
it's not a GCC bug, especially since it is coming and going depending
on GCC commits, and that you are using unreleased version of GCC?

P.S.  Please don't CC emacs-devel on bug reports, it causes problems
with the bug tracker, which sometimes creates bogus new bugs.
