           Summary: segfault with procedure pointer component
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal

The following code gives a segmentation fault.

    integer, intent(in) :: n
    real, intent(in), dimension(:) :: x
    real, dimension(n,n) :: dum_tfunc
    dum_tfunc = 0
  end function dum_tfunc
end module element_defs_m
module m1
  use element_defs_m

  subroutine scalar_diffusion2_elem ( coefficients)
   type(coefficients_t), intent(in) :: coefficients
