  Catch a possible NULL pointer deref in case the offsets got mangled
  somehow.
  As a consequence we may now get an unexpected result(*).
  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.
