Hi, I'm very much out of my depth here so I can only hope I'm including enough information here. I recently downloaded Mesa version 3.1. The only thing I've tested it against is xscreensaver, and I was pleased to see that it now runs the "lament" hack flawlessly. It used to crash. The only thing I've noticed so far that doesn't work is the "extrusion" hack, which also relies on the GLE library (see http://linas.org/gle). It works fine until you try the "twistoid" shape (extrusion -name twistoid) which hangs on the first call to gleTwistExtrusion(), i.e. pretty much at once. I tracked it as far as extrusion_angle_join() until I gave up and ran it in a debugger instead. After a while it seemed to be stuck in what it claimed was output_contours(), line 1522 of tess_clip.c: vertex = clip->proxy->vertices[LEFT]; do { num_vertices++; vertex = vertex->next; } while ( vertex != clip->proxy->vertices[LEFT] ); At this point, num_vertices exceeded 40,000 which suggested an infinite loop so I looked at the value of vertex for a while: 1: vertex = (tess_vertex_t *) 0x80a9cf8 <---- 1: vertex = (tess_vertex_t *) 0x80a9d48 1: vertex = (tess_vertex_t *) 0x80a9d98 1: vertex = (tess_vertex_t *) 0x80a9de8 1: vertex = (tess_vertex_t *) 0x80a9e38 1: vertex = (tess_vertex_t *) 0x80aa108 1: vertex = (tess_vertex_t *) 0x80a9f28 1: vertex = (tess_vertex_t *) 0x80aabe0 1: vertex = (tess_vertex_t *) 0x80a9b18 1: vertex = (tess_vertex_t *) 0x80a9b68 1: vertex = (tess_vertex_t *) 0x80a9bb8 1: vertex = (tess_vertex_t *) 0x80a9c08 1: vertex = (tess_vertex_t *) 0x80a9c58 1: vertex = (tess_vertex_t *) 0x80a9ca8 1: vertex = (tess_vertex_t *) 0x80a9cf8 <---- (gdb) print clip->proxy->vertices $45 = {0x80aa0b8, 0x80aa068} I don't know if this is a problem with Mesa, but it did work file with Mesa 3.0. I'm running an "unstable" Debian distribution on a Pentium III, 64 MB RAM. Kernel 2.2.12, Mesa 3.1, GLE 2.3, xscreensaver-3.22, XFree86 3.3.5, GCC 2.95.2... I'm not sure what other information may be useful, so please contact me if I can be of any help.
