If you can reliably trigger the problem by switching versions and you
are still curious and want to spend a little more time on it, you may be
able to bisect the fix to solve the mystery.

Keep in mind that you are bisecting a fix, not a regression, so your
meanings of "good" and "bad" will be opposite of what you expect. I.e.,
"bad" commits will have the fix, and "good" commits will not (I know
this is confusing; it's an artifact of the way bisect works).
