I'm still trying to hunt down where this SIGILL I'm hitting is coming from, and the next obstacle I've hit is some missing debuginfo packages, specifically:

libGLEW-debuginfo

libXau-debuginfo

libXext-debuginfo

mesa-libGLU-debuginfo

Any chance those could be added the the debuginfo repository?

Without them gdb chokes before it gets to the SIGILL line.
