Bug ID: 113118
Summary: ICE on assignment of derived types with allocatable
class component
Product: gcc
Version: 13.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: baradi09 at gmail dot com
Target Milestone: ---
I get an internal compiler error with the following demo code. As far, as I can
judge, the code is standard conforming.
module bugdemo
implicit none
type :: base_type
character(:), allocatable :: name
end type base_type
type :: base_type_item
class(base_type), allocatable :: item
end type base_type_item
type, extends(base_type) :: derived_type
integer :: val = 0
end type derived_type
contains
function derived_type_as_item(name, val) result(item)
character(*), intent(in) :: name
integer, intent(in) :: val
type(base_type_item), allocatable :: item
item = base_type_item(derived_type(name=name, val=val))
end function derived_type_as_item
end module bugdemo
Compiling it with
gfortran -c bugdemo.f90
results in
23 | item = base_type_item(derived_type(name=name, val=val))
