I've created bug 61904 for this:

  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61904

Note that I don't personally have a reproducer (my machine has
gcc-4.8.3, and I don't see the same behavior), but I included the
incorrect fair.s file that Michel sent me (which has all the command
line options in it), and a pre-processed "fair.i" source file that I
generated and that *should* match the configuration that was the
source for that result. So there might be some version/configuration
skew there between the two files, but I think they match.

Holler if you cannot reproduce the problem based on that.
