Re: [PATCH] revision: fix missing null for freed memory

Doing that shows that v2.37.0 is actually bad. And bisecting shows that
it has been broken since 087c745833 (log: add a --no-graph option,
2022-02-11), which is not too surprising.

Yeah, broken from its beginning is usually how these kinds of bugs
turn out to be.

I've also run into non-determinism when bisecting like this, because my
test command depends on the value of HEAD. The best solution here is to
just feed a stable tip to git-log. I bisected on:

  git log --graph --no-graph --patch origin >/dev/null

(I didn't need "-2" because good commits failed with "unrecognized
argument" and bad ones were killed by ASan immediately ;) ).

Thanks for sharing a good tip.
