a01b0bf0fbd870bec1747318bc081ac4a0606fb8 appears to be on the beta branch. I don't think this tool works with betas. Can you pick a revision from master?

[nagisa]

I can. I was just surprised at a very unintuitive message. FWIW I took a revision from master that did not happen to be a merge by bors and it failed the same way.

[ehuss]

Ah, yea, the error could definitely be better. I use git log --first-parent to make sure I'm looking at bors-only commits.

This still appears to be an issue, even if the target commits are on master:

@ngc0202 cargo-bisect-rustc doesn't work with old commits like 879e8aa7be06a53cd6cd9cc714e85a13c909c0ea. IIRC, the max commit age is 167 days. The error could be better, but what you're trying won't work. Nightlies are available all the way back, although 2014 might be too old, too.
