--- Comment #8 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Results with the patch in comment 5 at
https://gcc.gnu.org/ml/gcc-testresults/2014-12/msg02164.html.

Note that the test gfortran.dg/assumed_rank_10.f90 fails at run time when
compiled with '-O2 -funroll-loops -m32'. Without '-funroll-loops' the test
succeeds at run time.
