It means you've had a crash.  Signal 11 is `segmentation-fault'
(general protectiong fault in Windows speak).  Normally it tries
to map this into a Prolog exception.  If, while trying to recover,
it gets a second one it generates a system error saying: ``I'm lost''.

If it can be reproduced and you are running a recent release, please
submit the program in a bug-report.
