Not sure off the top of my head, other than some potentially newer  
things you're trying to do on HW which doesn't support it. The  
invalid enumeration might happen inside your object's draw code  
rather than inside ob3d_draw_end, and we're simply reporting the  
error there. You can try adding jit_gl_report_error("doing some thing  
in my object") to various places in your object's code, which is  
essentially a wrapper for glGetError() and post(), to see if it's  
happening elsewhere.

Another thing that you might find useful is that even on Intel, you  
should be able to test the PPC portion of your UB object by selecting  
"Open Using Rosetta" for MaxMSP 4.6.3 in the GetInfo window. This  
should load Max and any externals as PPC.

Good luck, and thanks for sharing such an excellent object with the  
community.
