--- Comment #1 from Gaius Mulley <gaius at gcc dot gnu.org> ---
Confirmed - it appears that the gcc/m2/gm2-compiler/M2Quads.mod:BuildRelOp
procedure is generating incorrect quadruples.  During processing of the
inequality it detects the two boolean sub expressions and manipulates them =
to
deduce the result.  However the manipulation has ignored the operands c and=
 d
require de-referencing.=
