Bug ID: 125608
Summary: ICE in polymorphic assignment to array com
Product: gcc
Version: 15.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: townsend at astro dot wisc.edu
Target Milestone: ---
The following code triggers an ICE on aarch64 and x86-64:
--
program test_poly_assign
implicit none
type :: foo_t
end type foo_t
type :: bar_t
class(foo_t), allocatable :: foo
end type bar_t
type(foo_t) :: foo
class(bar_t), allocatable :: bar(:)
allocate(bar(1))
bar(1)%foo = foo
end program test_poly_assign
--
Compiling with gfortran -c test_poly_assign.f90 on x86-64 gives
test_poly_assign.f90:16:19:
16 | bar(1)%foo = foo
| 1
internal compiler error: in gfc_get_descriptor_field, at
