Sorry if I seem to be a bit slow (I've caught a bronchitis again
and perhaps cannot think as clearly as I should)... So you think
the error is in m3-sys/m3front/src/exprs/SetExpr.m3 in

PROCEDURE Compare (a, b: Expr.T;  VAR sign: INTEGER): BOOLEAN =
and
PROCEDURE Visit (VAR s: VisitState): BOOLEAN =

or rather in m3middle while writing the intermediate representation?
