            Bug ID: 57912
           Summary: gfortran/coarray/alloc_comp_2.f90 ICE
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal

         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: belagod at gcc dot gnu.org

On the trunk, gfortran(f951) ICEs when compiled with 

.../obj/gcc/f951 .../gcc/gcc/testsuite/gfortran.dg/coarray/alloc_comp_2.f90
-fcoarray=lib  -O2

This ICE goes away when this commit is reversed:

commit 435feecde2fc6bf5627aad91805bbd69ddbbe830

            * trans-array.h (gfc_deallocate_alloc_comp_no_caf,
            gfc_reassign_alloc_comp_caf): New prototype.
            * trans-array.c (enum): Add DEALLOCATE_ALLOC_COMP_NO_CAF
            and COPY_ALLOC_COMP_CAF.
            (structure_alloc_comps): Handle it.
            (gfc_reassign_alloc_comp_caf,
            gfc_deallocate_alloc_comp_no_caf): New function.
            (gfc_alloc_allocatable_for_assignment): Call it.
            * trans-expr.c (gfc_trans_scalar_assign,
            gfc_trans_arrayfunc_assign, gfc_trans_assignment_1): Ditto.
            * parse.c (parse_derived): Correctly set coarray_comp.
            * resolve.c (resolve_symbol): Improve error wording.

    2013-07-15  Tobias Burnus  <burnus@net-b.de>

            * gfortran.dg/coarray_lib_realloc_1.f90: New.
            * gfortran.dg/coarray/lib_realloc_1.f90: New.
            * gfortran.dg/coarray_6.f90: Add dg-error.

I observed this behaviour on a trunk compiler built native on
x86_64-unknown-linux-gnu.
