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

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.

Passes without -ffast-math.

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
/home/jye2/cpu2000/benchspec/CFP2000/172.mgrid/run/0003/mgrid.out.mis

No small case available yet

Works for me.  Very likely a dup of PR36967.
