Hazen, Is there any way you could get a backtrace on this from gdb or otherwise? I do not have access to a PPC Mac to test on at this time and a search on Google for "cairo bus error" gives lots of OSX-related results but no answer that seems obvious to me. Does example 20 work with other Cairo devices on your PPC OSX system? plimage/plimagefr + any Cairo device uses a similar offscreen rendering method to rasterize the plotted image. That code has been in Subversion since late May and has no specific ties to X or xcairo. Hez -- Hezekiah M.
