  SVN rev 196538 on 2009-08-25 12:32:16Z by bz
  
  MFC r182842:
  
    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.
