Bug #: 55854
Summary: ICE on intent(out) dummy argument with unlimited
polymorphic component
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: dam...@rouson.net
As demonstrated below, having an "intent(out)" dummy argument with an
unlimited polymorphic component generates an internal compiler error
with a December 23 build of gfortran 4.8:
$ cat ice_on_intent_out_with_unlimted.f90
type foo
class(*), allocatable :: x
end type
contains
subroutine bar(this)
type(foo), intent(out) :: this
end
end
$ gfortran ice_on_intent_out_with_unlimted.f90
ice_on_intent_out_with_unlimted.f90: In function 'bar':
ice_on_intent_out_with_unlimted.f90:5:0: internal compiler error:
Segmentation fault: 11
subroutine bar(this)
