Here's the dump with the patch: http://bayfiles.net/file/PnC9/us249L/glxgears_new.gz Please note that the behavior you relied on - implicit zeroing of C++ class members - is unreliable in other compilers too. I find it's also bad practise not to init members in the constructor if you expect them to have some particular value. - Lauri _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
