  This is a fix for a bug found by adding new fields to the
  OP structure which caused a segmentation fault during the
  code generation phase when building SPEC dealII.
  
  The Base() member function of a POINTS_TO structure only
  returns a valid ST pointer when the base kind is fixed (for
  debugging purposes, during alias information construction
  pointers to different structures are placed in _base when
  the base kind is dynamic).
  
  For consistency sake, in this source file I changed the
  other check to determine whether the base kind is fixed to
  use the Based_is_fixed() member function.
