So, I don't mean for this to be a lesson in gdb. I was able to build Xorg with 
debugging symbols easily. When I start gdb and run 'continue' before Xorg 
crashes, nothing happens. It doesn't even bring me back to a (gdb) prompt. When 
I try to exit out of gdb, then Xorg crashes. I was expecting a (gdb) prompt 
after continue where I can wait for the segfault and run "bt full".
