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.
