Sure, this is really no problem, I also tried it before, but as soon as I
attach gdb (via PID specification) X's execution seems to stop (and I need it
to continue to run to trigger the error...). Probably I just need to tell to
"continue" or something but I did not find anything in the man page (quickly
reading). If you could tell me how to attach and continue to run X and then
backtracing ...  Hmm, I just found
http://visualgdb.com/gdbreference/commands/continue which tells me that I just
need to issue the command "continue". Does it work this way (we have no
breakpoints).

Well, I guess it is related to the different monitor sizes, so you likely only
can reproduce it with a bigger / smaller external VGA monitor.
