Subject: Seg Fault on git fetch with fetch.negotiationAlgorithm=skipping
Message-ID: <450D5CC7-113A-40D8-9CD4-53786198526D@gmail.com>

Hi folks,

We recently encountered a segfault during a git fetch
strace output could be found https://gist.github.com/sluongng/e48327cc911c617ed2ef8578acc2ea34

The root cause was due to having `fetch.negotiationAlgorithm=skipping`
The repo is about linux.git size with a few NULL commit that we have been using `fsck.skipList` 
on both server and client side to skip.

Is this and edge case for the new algorithm?

Cheers,
Son Luong.
