The abort is here (in get_local_map):

  /* Perhaps we should just change `position' to the limit.  */
  if (position > BUF_ZV (buffer) || position < BUF_BEGV (buffer))
    emacs_abort ();

The caller, Fcurrent_active_maps, checks a different condition before
the call:

              pos = POSN_BUFFER_POSN (position);
              if (INTEGERP (pos)
                  && XINT (pos) >= BEG && XINT (pos) <= Z)
                {
                  local_map = get_local_map (XINT (pos),
                                             current_buffer, Qlocal_map);


So perhaps the bug is in the caller: it should test BEGV and ZV
instead of BEG and Z.
