Created attachment 15185 [details] Backtrace and disassembly System: Ubuntu 8.04 development version amd64 arch. CPU: Intel Core2 Duo Graphics: Intel i945 The file src/mesa/x86-64/xform4.S in Mesa contains at least one Opcode that is AMD-specific (pfmul, pfadd is 3DNow only). Since x86_64 is no longer AMD-specific this causes an invalid opcode exception and the program crashes. I'll attach a backtrace + disassembly showing where the problem appears. To reproduce: Run any opengl-app that uses _mesa_x86_64_transform_points4_3d_no_rot on a x86-64 machine, with 64-bit userland and an Intel CPU.
