Confirmed. Test case:

namespace sc_dt {
    class sc_length_param {
	friend int compare_unsigned(int if_v_signed = 0);
    };
}

[Bug c++/13166] DR136 not implemented

[lerdsuwa at gcc dot gnu dot org]

------- Additional Comments From lerdsuwa at gcc dot gnu dot org  2003-12-05 14:49 -------
The regression is fixed in the mainline.  So it no longer ICE.
However the behavior mentioned in DR136 (limiting which friend
declaration can have default function argument) is not yet implemented.
So I keep this bug report open, change keywords into an accept-invalid
and adjust the summary accordingly.
