--- Comment #5 from avieira at gcc dot gnu.org ---
Yeah...

So far I have checked that 'gimplify_call_expr' creates the right gimple, a=
nd
up until 'gimplify_modify_expr' I can verify it does by using
gimple_call_fntype .

Though at expansion time, the 'gimple_call_fntype (stmt)' of '_5 =3D s_bar_=
p_2(D)
(); [tail call]' now has the attribute ...

So it must go wrong somewhere between gimplification and expansion, but tha=
t's
a big window and dump files won't help us :(=
