more specific please. Is this with direct rendering (in which case component should be drivers/dri/mach64) or are you using for some or another reason an indirect rendering fallback (LIBGL_DEBUG=verbose glxinfo should answer that). Also, are you using mesa cvs or what? Looked like that function was in the body of the library, sorry. Changing component. Mesa from CVS on client side, but it's been segfaulting since 6.3.x, only just recently tried it again and got a trace. Server side is xorg from cvs, built with Mesa source from 6.4 branch, as it doesn't build against "6.5" Closing after 7 years of silence. I think it's safe to assume this is fixed in current mesa, as the backtrace shows no mach64 driver functions, and AFAICT there were no problems with vertex handling in mesa/main recently. Anyway, mach64 is no longer supported by mesa. |
