That the bug went away is a fluke. It wasnt fixed.
It is in pb-preprocess, an essentially unused tactic. The special subsumption resolution rule wasn't accounting for membership of all variables.

Add an alternative to unit-subsume-simplify
It is called solver-subsumption
It does a little more than unit-subsume-simplify and also uses a different decomposition algorithm for clauses.
It removes redundant constraints and simplifies clauses in a single pass.
A possible use of this tactic is in isolation where the maximal number of conflicts
(smt.conflicts_max, sat.conflicts_max) are bounded. For simpler formulas full solver calls may be still feasible.
