Bjoern A. Zeeb 6f4745d575 Catch a possible NULL pointer deref in case the offsets got mangled ...

somehow.

Catch that error cases with a well defined panic giving appropriate
pointers to ease debugging.

(*) While the concensus was that the case should never happen unless
    there was a bug, noone was definitively sure.
