Hi @jacquesguan  @topperc . You have mentioned that breaking at calls in `emitSelectPseudo` would fix the issue, but it is not the root cause of the it. In the current state of things, we are generation wrong code if the assertions are disabled. Could we please at least temporarily do the above mentioned quick fix in `emitSelectPseudo` so we are not generating wrong code? Would that work @topperc ? If so would you @jacquesguan like to do it or should I create a PR with that?

Thank you.
