Bug ID: 79229
Summary: [7.0.1 regression] ICE in gfc_trans_assignment_1 with
-fcheck=mem
Product: gcc
Version: 7.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: juergen.reuter at desy dot de
Target Milestone: ---
The following code leads to an ICE when compiled with -fcheck=mem
(without the flag, it compiles):
$ gfortran -fcheck=mem -c sf_isr_uti.f90
sf_isr_uti.f90:19:0:
allocate (t3 :: sf_int (2))
internal compiler error: in gfc_trans_assignment_1, at
fortran/trans-expr.c:9964
sf_isr_uti.f90:19:0: internal compiler error: Abort trap: 6
Code that triggers the ICE:
module uti
implicit none
private
type, abstract :: t1
end type t1
type :: t2
end type t2
type, extends (t1) :: t3
private
type(t2), pointer :: data => null ()
end type t3
contains
subroutine s_1 ()
class(t1), dimension(:), allocatable :: sf_int
allocate (t3 :: sf_int (2))
end subroutine s_1
end module uti
