Bug ID: 124598
Summary: (PDT) - ICE instantiating nested PDTs
Product: gcc
Version: 15.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: [email protected]
Target Milestone: ---
ICE with gfortran 14.3.1 and gfortran 15.2.1
Minimal example:
program test_pdt
implicit none
type t_foo
integer :: c
end type t_foo
type t_bar(n)
integer, len :: n = 1
type(t_foo) :: foo(n)
end type t_bar
type t_baz(n)
integer, len :: n = 1
type(t_bar(n)) :: bar(n)
end type t_baz
type(t_baz(n)) :: baz ! <- REMOVE THIS LINE AND THIS PROGRAM COMPILES
end program test_pdt
Compilation command:
$ gfortran -g -freport-bug -o test_pdt main.f90
main.f90:19:20:
