Okay. I'm going to apply this patch, but because the elfloader object
isn't even in the debugging server (because the modules are linked
directly into the huge XFree86-debug object), this isn't the real
problem you're seeing.
It may be necessary to attach gdb to the XFree86-debug server from a
remote terminal to locate the source of the problem.
Unless you can ulimit -c unlimited and get a good backtrace off the core
from XFree86-debug?
