--- Comment #3 from Jan Hubicka <hubicka at ucw dot cz> 2011-11-15 12:37:07 UTC --- > gfortran.fortran-torture/execute/arrayarg.f90 is miscompiled. There are 4 expanded memset calls in the testcase, all ends up being unrolled loop. Looks like we misoptmize one of them. I am looking into that. Honza
