            Bug ID: 69603
           Summary: ICE: segfault with -fimplicit-none and
                    proc_ptr_comp_24.f90
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gerhard.steinmetz.fortran@t-online.de
  Target Milestone: ---

While playing around, one example from ./gcc/testsuite/gfortran.dg/
together with option -fimplicit-none segfaults :


$ gfortran-6 -fimplicit-none -c proc_ptr_comp_24.f90
f951: internal compiler error: Segmentation fault


$ gfortran-5.3.1 -fimplicit-none -c proc_ptr_comp_24.f90
f951: internal compiler error: Segmentation fault


Whereas, no error/ICE with :

$ gfortran-6 -c proc_ptr_comp_24.f90
$ gfortran-5.3.1 -c proc_ptr_comp_24.f90


Example originates to pr42045.
