Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org

Started with r6 (z%g= is invalid, r5 compiles it) :
$ cat z1.f90
module m

type t
procedure(f), pointer, nopass :: g
end type
contains
function f()
character(:), allocatable :: f
f = 'abc'
end
subroutine s
type(t) :: z
z%g = 'x'
if ( z%g() /= 'abc' ) stop
end
end
program p
use m
implicit none
call s
end
$ gfortran-5 -c z1.f90

Fortran: Fix an assortment of bugs

PR fortran/105152
* interface.cc (gfc_compare_actual_formal): Emit an error if an
unlimited polymorphic actual is not matched either to an
unlimited or assumed type formal argument.
PR fortran/100193
* resolve.cc (resolve_ordinary_assign): Emit an error if the
var expression of an ordinary assignment is a proc pointer
component.
PR fortran/87496
* trans-array.cc (gfc_walk_array_ref): Provide assumed shape
arrays coming from interface mapping with a viable arrayspec.
PR fortran/103389
* trans-expr.cc (gfc_conv_intrinsic_to_class): Tidy up flagging
of unlimited polymorphic 'class_ts'.
(gfc_conv_gfc_desc_to_cfi_desc): Assumed type is unlimited
polymorphic and should accept any actual type.
PR fortran/104429
(gfc_conv_procedure_call): Replace dreadful kludge with a call
to gfc_finalize_tree_expr. Avoid dereferencing a void pointer
by giving it the pointer type of the actual argument.
PR fortran/82774
(alloc_scalar_allocatable_subcomponent): Shorten the function
name and replace the symbol argument with the se string length.
If a deferred length character length is either not present or
is not a variable, give the typespec a variable and assign the
string length to that. Use gfc_deferred_strlen to find the
hidden string length component.
(gfc_trans_subcomponent_assign): Convert the expression before
the call to alloc_scalar_allocatable_subcomponent so that a
good string length is provided.
(gfc_trans_structure_assign): Remove the unneeded derived type
symbol from calls to gfc_trans_subcomponent_assign.
