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.
