git gc error with git 2.37.2? (Introduced in 5a5ea141e7)

[Paul Wagland <pwagland@gmail.com>]

Hi all,

On git-users, I started a discussion(*) about a git gc error that I was getting that started with git 2.37.2. After some followup from Mathias on that list, I have determined that the issues that I a having started with the following commit:  https://github.com/git/git/commit/5a5ea141e7 ("revision: mark blobs needed for resolve-undo as reachable", 2022-06-09)

When I compile git locally with:
   git checkout dc8c8deaa6
   make
   git rev-list --objects --indexed-objects

Then it works.

   git checkout 5a5ea141e7
   make
   git rev-list --objects --indexed-objects

Then I get the error:
   fatal: missing blob object ‘1d0f34d1c4314efcff527847755e4ccc77d44fb6'

How can I further diagnose how to fix this?

Cheers,
Paul
