--- Comment #63 from David Binderman <dcb314 at hotmail dot com> --- (In reply to Martin Liška from comment #62) > Can't reproduce with the current master: Righto. This is proving unexpectedly hard to reproduce. EITHER: I search various values of march= to find out which ones work and which ones don't. OR: I do a fishing trip for revisions some unknown time before 2020-06-11 (the known bad date), to find a known good date, then run git bisect from there. In furtherance of option 2 and given that Jun 2020 is long enough ago that the git rev-list will have expired (it is only valid for 90 days), am I correct in thinking that something like git rev-list -n 1 --first-parent --before="2020-01-01" master will give me a git hash of a revision of the first day of year 2020 and so git checkout `that git hash` will get me to that date, so I can run a build ?
