Thanks for the response.

You are right: the code generated by 4.9 and trunk gcc is correct -- after
going back and rebuilding and retesting I am seeing the same code you posted.
I'm not sure what I did wrong the first time; sorry for the spam / noise /
false alarm. I will mark the bug as INVALID...

The specific copy of gcc I'm working with (which as you pointed out I should
have included in the original report) is the Android platform/NDK copy of gcc
4.9, which is a variant based on the
svn://gcc.gnu.org/svn/gcc/branches/google/gcc-4_9 branch with the addition of
some changes back-ported from trunk.

I can reproduce the same problem by building directly from the gcc
google/gcc-4_9 branch (no Android changes), so it looks as though that is where
things went off the tracks.
