            Bug ID: 62289
           Summary: [5 Regression] ICE (segfault) for
                    gfortran.dg/graphite/pr42393.f90
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org

Calling

  gfortran -O2 -fgraphite-identity -fno-loop-block -fno-loop-interchange
-fno-loop-strip-mine gfortran.dg/graphite/pr42393.f90

or running the testsuite fails for the test case with

gfortran: interner compiler error: segfault (program f951)
0x40d28c execute
        ../../gcc/gcc.c:2900
0x40d4b9 do_spec_1
        ../../gcc/gcc.c:4704

That's with r214616; the system has ISL 0.12 and CLooG 0.18.0; a grep in
config.log shows:

gcc_cv_cloog=no
gcc_cv_isl=yes
clooginc=''
clooglibs=''
extra_isl_gmp_configure_flags=''
islinc='-DCLOOG_INT_GMP '
isllibs=' -lisl'
