It certainly sounds like a challenging bisect, yes. I've 'bisect skip'ed and then 'git stash save' / 'git stash apply' a handful of work-arounds to narrow down hard cases like this before. It's also worth keeping in mind that you can insert steps manually into a bisect. For something like this where v2019.01 works and HEAD doesn't, I'd do: $ git bisect start $ git bisect good v2019.01 $ git bisect bad v2019.10-rc3 $ git checkout v2019.04 and see what happens. -- Tom
