Bug #: 55959
Summary: [OOP] ICE in in gfc_simplify_expr, at
fortran/expr.c:1920
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
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/msg00108.html.
Corrected test case:
module pdfs
type, abstract :: pdf
integer dims
contains
procedure(getx), deferred :: getx
end type pdf
abstract interface
function getx(this)
import pdf
class(pdf), intent(in) :: this
real getx(this%dims)
end function getx
end interface
type point
real x, y
end type point
type, extends(pdf) :: pdf_point
type(point) p
contains
procedure :: getx => pdf_point_getx
end type pdf_point
contains
function pdf_point_getx(this)
class(pdf_point), intent(in) :: this
real pdf_point_getx(this%dims)
pdf_point_getx(1) = this%p%x
pdf_point_getx(2) = this%p%y
end function pdf_point_getx
end module pdfs
program abstract
use pdfs
type(pdf_point) pp
namelist /nml_pp/ pp
print nml_pp
print pp%getx()
end program abstract
This produces the following ICE:
