I am getting it, too, but I remembered to save my repo. :) The 'next' branch is broken, but master works fine. The bisect points to commit 9441b61dc5c3f1f984114ec8bd470dc20c55dfe0 Author: Nicolas Pitre Date: Fri Oct 17 15:57:57 2008 -0400 index-pack: rationalize delta resolution code but I don't have time to look further right now (there is a small child who apparently thinks coloring with crayons is more interesting than bisecting bugs). I can make my broken repo available if need be (though given the number of us seeing the problem, I doubt it is hard to reproduce). -Peff ``` ## Nicolas Pitre, 2008-10-20 13:59 Subject: Re: [BUG?] Fail to pull from kernel.org: pack has bad object Message-ID: URL: https://gitlist.dev/e/alpine.LFD.2.00.0810200955250.26244%40xanadu.home In-Reply-To: <20081020121533.GA2177@coredump.intra.peff.net> ``` On Mon, 20 Oct 2008, Jeff King wrote: > I am getting it, too, but I remembered to save my repo. :) The 'next' > branch is broken, but master works fine.

It certainly is... to me at least. When index-pack dies like that, a temporary (and incomplete) pack file is left in .git/objects/pack/ with tmp in the file name. I'd need only that to reproduce the issue.

See the latest patch I just posted to the list. Nicolas ```
