With todays cvs (GNU gdb 6.3.50.20050126-cvs) I no longer get an internal
error but everything hangs instead. I presume that it is GDB hanging and
not Emacs, as Emacs does not hang at this place when its not running under
debug (I'm only splitting a window).

However, I don't know how to get a backtrace as sending SIGINT (actually
SIGSTOP with Emacs) interrupts the bottom level process (Emacs in this
case). I can then interrupt the GDB being debugged, but presumably by then
things have changed.
