Manuel López-Ibáñez <manu at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |manu at gcc dot gnu.org --- Comment #1 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- There is also this example: odr_type get_odr_type (tree type, bool insert) { .... odr_types[val->id] = 0; gcc_assert (val->derived_types.length() == 0); if (odr_types_ptr) val->id = odr_types.length (); .... } which is even more insidious since it is hidden behind macros.
