I built XFree86 from the DRI tree with -g as well as "#define
GlxBuiltInRadeon YES" in the host.def in order to try and get an almost
usable backtrace.
After having crashed X by switching to VT and back (at least this is 100%
reproducible) I attached to the process with gdb (ssh'd from another
machine). I've attached the backtrace... it has a tad more detail than
normal, but is there a way to get something a little more verbose?
Maybe this shakes some marbles in some of the developers' heads (in a most
pleasant manner, of course).
Any more ideas would be greatly appreciated,
Charl
