[Bug fortran/15181] New: gfc_conv_component_ref: Assertion `c->backend_decl' failed

["olchansk at panix dot com" <gcc-bugzilla@gcc.gnu.org>]

cvs-head tree-ssa gfortran (gcc version 3.5-tree-ssa 20040423 (merged 20040414))
fails to compile this code. It works fine with Absoft and ICC.

module foo
  implicit none

  type:: wire_type
     integer iwire
  end type wire_type

  type:: tdc_type   
     integer iabc
     type(wire_type), pointer:: wireP
  end type tdc_type

  type(tdc_type):: pctdc(100)

contains

  subroutine bar
    integer ii
    integer itdc

    !! following line causes ICE:
    !! f951: ../../gcc/gcc/fortran/trans-expr.c:219:
    !! gfc_conv_component_ref: Assertion `c->backend_decl' failed.

    ii = PCtdc(iTDC)%WireP%iwire

  end subroutine bar

end module foo
