             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: unassigned@gcc.gnu.org
        ReportedBy: janus@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:
