--- Comment #3 from janus at gcc dot gnu.org 2012-11-24 14:08:58 UTC ---
Further reduced test case, based on comment 1:

module Args_Basic_type_F03
  use, intrinsic :: iso_c_binding
  type Args_Basic_t
    type(c_ptr) :: d_ior = c_null_ptr
  end type
contains
  subroutine cache_epv_s(self)
    class(Args_Basic_t) :: self
  end subroutine
end module

  use Args_Basic_type_F03
  type, extends(Args_Basic_t) :: Args_Basic_impl_t
  end type
  type(Args_Basic_impl_t) :: obj
  call cache_epv_s(obj)
contains
  real function passeverywherechar_impl(self)
    type(Args_Basic_impl_t) :: self
  end function
end


This still ICEs with:

gcc version 4.6.4 20121124 (prerelease) [gcc-4_6-branch revision 193777] (GCC)
