It's probably the same / closely related issue. ISTM that JITed deforming either doesn't deform correctly, or skips deforming erroneously. I'm about to commit some changes to 12/master that'd possibly make it easier to find issues like this. Is there any chance that it's easier to repro this on master than making a reproducible test case? Greetings, Andres Freund
