Bug ID: 99585
Summary: ICE with SIZE intrinsic on nested derived type
components
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: anlauf at gcc dot gnu.org
Target Milestone: ---
As reported by Tobias Burnus in
https://gcc.gnu.org/pipermail/fortran/2021-March/055815.html
the following code ICEs with all gcc since at least 7:
module m
type t
class(*), pointer :: bar(:)
end type
type t2
class(t), allocatable :: my(:)
end type t2
contains
function f (x, y) result(z)
class(t) :: x(:)
class(t) :: y(size(x(1)%bar))
type(t) :: z(size(x(1)%bar))
end
function g (x) result(z)
class(t) :: x(:)
type(t) :: z(size(x(1)%bar))
end
subroutine s ()
class(t2), allocatable :: a(:), b(:), c(:), d(:)
class(t2), pointer :: p(:)
c(1)%my = f (a(1)%my, b(1)%my)
d(1)%my = g (p(1)%my)
end
end

Reduced example:
module m
type t
end type
type t2
type(t), allocatable :: my(:)
end type t2
contains
function h (x) result(z)
class(t2) :: x(:)
type(t) :: z(size(x(1)%my))
end
subroutine s ()
type(t2), allocatable :: a(:)
type(t), allocatable :: u(:)
u = h (a)
end
end

--- Comment #2 from anlauf at gcc dot gnu.org ---
Actually the SIZE intrinsic might be a red herring, as the following variant
does also ICE:
module m
type t
end type
type t2
integer :: n
end type t2
contains
function h (x) result(z)
class(t2) :: x(:) ! ICE
! type(t2) :: x(:) ! no ICE
type(t) :: z(x(1)%n)
end
subroutine s
type(t2), allocatable :: a(:)
type(t), allocatable :: u(:)
u = h (a)
end
end
