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.
