Bug #: 55960
Summary: [OOP] ICE in replace_comp, at fortran/expr.c:4356
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: ja...@gcc.gnu.org
Reported at http://gcc.gnu.org/ml/fortran/2013-01/msg00109.html.
Reduced test case:
module pdfs
type, abstract :: pdf
contains
procedure(getdims), deferred :: getdims
procedure(getx), deferred :: getx
end type pdf
abstract interface
pure function getdims(this)
import pdf
class(pdf), intent(in) :: this
integer getdims
end function getdims
pure function getx(this)
import pdf
class(pdf), intent(in) :: this
real, dimension(getdims(this)) :: getx
end function getx
end interface
end module pdfs
Yields the ICE:
