That is not the right fix.  It is documented in hlds_goal.m as
an invariant of the HLDS that the cons_id in a unify_rhs is never
a pred_const.  So either the invariant needs to be changed, or (IMHO
more likely) the code which produces such a unify_rhs needs to be fixed.

BTW, when did the highorder test start failing, and what options caused
it to fail?  It seems to have been working fine previously.
