CC some ARM maintainer.

It would be tremendously useful narrow down the versions a bit more; there have
been 90 commits to 4.5 between -r167945:170352 on 4.5 (ignoring gccadmin
DATESTAMP bumps).

Additionally, it would be interesting to know whether the 4.6 trunk is affected
as well. I tried to figure this out from gcc-testresults, but there seem to be
only very few arm-linux-gnueabi results and, additionally, most of the arm-*-*
results do not include Fortran.

As the issue seems to occur only for
  -O3 -fomit-frame-pointer -funroll-all-loops (-finline-functions)
it might well be a middle-end/target issue. (Though it could still be a
front-end issue.)
