[Bug fortran/42597] New: ICE with procedure pointer initialized to null()

["mrestelli at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The attached code (which seems fine to me) produces an internal
compiler error.

gfortran -c pp.f90 -o pp.o
f951: internal compiler error: in gfc_build_null_descriptor, at
fortran/trans-array.c:372

gfortran --version
GNU Fortran (GCC) 4.5.0 20091229 (experimental)


module mod_a
 implicit none
 public :: p_fun
 private

 abstract interface
  pure function intf(x) result(y)
   real, intent(in) :: x(:,:)
   real :: y(size(x,1),size(x,1),size(x,2))
  end function intf
 end interface

 !procedure(intf), pointer :: p_fun ! this works
 procedure(intf), pointer :: p_fun => null()

end module mod_a
