Corrupt repo with force push when using a reference repo

Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

With 3 clones of a repo, one on branch-a one a mirror,  another using the mirror as a reference repo on branch-b, do the following

# in the repo on branch-a, make a change, commit and push cd bad-object-test echo $(( RANDOM % 1000 + 1 )) > file.txt git ci -am "change a file" git push

# do a git fetch in the reference repo cd ../bad-object-test.git/ git fetch

# do a git pull in the repo on branch-b cd ../bad-object-test-with-reference-repo/ git pull

# All good so far

# in the repo on branch-a, discard HEAD and force push cd ../bad-object-test git reset --hard HEAD~1 git push --force

# do a git fetch in the reference repo and then prune loose objects cd ../bad-object-test.git/ git fetch git prune -v --expire=now

# do a git pull in the repo on branch-b cd ../bad-object-test-with-reference-repo git pull

What did you expect to happen? (Expected behavior)

the repo on branch-b does a force update of romote tracking branch branch-a

What happened instead? (Actual behavior) xxx> git pull fatal: bad orefs/remotes/origin/branch-a error: https://github.com/xxxxx/yyyyyyy.git did not send all necessary objects

What's different between what you expected and what actually happened?

I expected the force push to succeed, but insted I get a corrupt repo

Anything else you want to add:

git rev-parse refs/remotes/origin/branch-a will return the hash of the commit that was discarded by the git reset command
