Re: [PyMOL] Ray Tracing Bug in Pymol 0.93 on SuSE Linux 8.2
Dear Buz, I've been using Pymol 0.93 on SuSE Linux 8.2 for a few hours now, and I'm having trouble ray tracing graphics. Each time I start the ray tracer Pymol quits with a segmentation fault error; I guess you are running into a compiler bug (or a bug in PyMol which gets exposed only by some compiler versions). For me PyMol on SuSE 8.2 crashed always when raytracing a line element. The stock compiler on SuSE 8.2 is gcc 3.3 20030226 (prerelease). I got the same crash with gcc 3.3.1, but not with gcc 2.95. I have not tried it on SUSE 9 yet, installing and using gcc 2.95 (for PyMol only) solved the problem for me. See PyMol bugreport 806361.

Re: [PyMOL] pymol raytracing crash
Dear Warren, I installed it with python distutils from source. See the bug report I filed in the meantime for details. It turned out to be a problem with some versions of gcc - crash when raytracing lines, sticks or meshes with gcc (GCC) 3.3 20030226 (prerelease) (SuSE Linux) and with gcc 3.3.1, but a perfectly stable PyMOL with good old gcc 2.95.3.
