Passes without -ffast-math.

More info:
1. Revision 138207 introduced ICE.
2. Revision 138318 fixed ICE, but miscompiled mgrid.
3. Revision 138207 + change in revision 138318 also miscompiled mgrid.

If you remove -ffast-math, does it miscompare?

Although 138318 fixes the compiler ICE, it miscompile with -O3 -ffast-math on
x86-64:
Running 172.mgrid ref base o3 default
*** Miscompare of mgrid.out, see

Works for me. Very likely a dup of PR36967.
