Yes, a bug was going to be reported one way or another, by Madhu or by me. This
test case seems to have uncovered two GCC bugs, one introduced in GCC 4.9.x in
2014, and one that seems to predate that. Richard Biener is testing an overall
patch.
I considered putting something into etc/PROBLEMS warning people not to compile
Emacs with gcc -O2 -Os, but apparently that sort of GCC usage is pretty rare so
it's not clear it's worth documenting it (plus, the advice is not specific to
Emacs).
