Thanks for the report. Of course gcc can also have bugs but it would look like you may not be doing a clean build or that some how object code from two different builds got mixed up. JIC, the cp_obj_protocol_id_list stuff is obviously objc stuff that we don't need at all and that crept in along with other changes from Apple so I will remove it to see if it helps somehow. Pedro.
