It isn't sufficient to tell Git that a commit that exhibits the bug is "old" and one that doesn't is "n= ew" because git-bisect actually wants to test some commits that do not have the bug-introducing commit as an ancestor. So, at each step of the bisection, I have to manually check that the bug-introducing commit (d019930b0049fc2648a6b279893d8ad330596e81) is actual= ly an ancestor of the current bisection step, and if it isn't, then the current step is definitionally "old": $ git merge-base --is-ancestor \ d019930b0049fc2648a6b279893d8ad330596e81 BISECT_HEAD || git bisect old --=20 You may reply to this email to add a comment.
