I can't reproduce the problem here, using core.gitproxy with a script identical to what you showed above. I tried both cloning, and fetching via both git-fetch and git-fetch-pack.

Can you show us a more complete example? What does the command that fails look like? What's the repo state before you run it? At what part of the conversation does it fail (before a pack is sent, during, or after)?

If you can reproduce it at will and it fails on 2.33 but not earlier, then bisecting might be helpful.
