That may have been a problem in the past, but it is no longer an issue now that the pipeline is fully operational with UBSAN enabled on both ARM and x86. Andrew also mentioned in chat that he supports enabling UBSAN in the pipeline as soon as possible. Since the pipeline remains green with UBSAN enabled and is not expected to suddenly go red before the release, I am requesting a release ack from Oleksii. Cheers, Stefano
