Bug ID: 114535
Summary: ICE with elemental finalizer
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: abensonca at gcc dot gnu.org
Target Milestone: ---
The following code (which must be in two files to trigger the error) causes an
ICE using the latest gfortran.
$ cat ice1.F90
module iv
type, public :: vs
contains
final :: destructor
end type vs
contains
elemental subroutine destructor(s)
type(vs), intent(inout) :: s
end subroutine destructor
end module iv
$ cat ice2.F90 module d
contains
function en() result(dd)
use :: iv
type(vs) :: dd
return
end function en
end module d
module ni
contains
subroutine iss()
use :: d
return
end subroutine iss
end module ni
$ gfortran -v
