* 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.

* 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.
