Bug ID: 98472
Summary: internal compiler error: in gfc_conv_expr_descriptor,
at fortran/trans-array.c:7352
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: ruicoelhopedro at hotmail dot com
Target Milestone: ---
This occurs during an allocation whose source is the result of an elemental
function in a polymorphic class.
Tested in versions 7.5.0, 9.2.1 and 10.2.0, report below is shown for version
10.2.0
$ cat mwe.f90
module a
type, abstract :: base
contains
procedure(elem_func), deferred, nopass :: add
end type base
type, extends(base) :: derived
contains
procedure, nopass :: add => add_derived
end type derived
abstract interface
elemental function elem_func(x, y) result(out)
integer, intent(in) :: x, y
integer :: out
end function elem_func
end interface
contains
elemental function add_derived(x, y) result(out)
integer, intent(in) :: x, y
integer :: out
out = x + y
end function add_derived
end module a
program main
use a
integer, dimension(:), allocatable :: vec
class(base), allocatable :: instance
allocate(derived :: instance)
allocate(vec, source=instance%add([1, 2], [1, 2]))
end program main
