Bug ID: 86242
Summary: [F03] ICE for derived type with allocatable class
component
Product: gcc
Version: 8.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: c...@mnet-mail.de
Target Milestone: ---
The following Fortran 2003 code (which compiles with flang 6.0,
pgfortran 17.10, and ifort 19.0.0.070 Beta) generates an internal compiler
error (ICE) with gfortran 8.0.1:
$ cat test.F90
module test
implicit none
private
public :: tester
type :: wrapper
integer(4) :: n
end type wrapper
type :: output
real(8) :: dummy
end type output
type :: tester
class(wrapper), allocatable :: wrap
procedure(proc1), pointer :: ptr => null()
end type tester
abstract interface
function proc1(self) result(uc)
import :: tester, output
class(tester), intent(in) :: self
class(output), allocatable :: uc
end function proc1
end interface
end module test
$ gfortran-8 -c test.F90
test.F90:29:0:
end module test
internal compiler error: Segmentation fault
