I can reproduce it reliably on both Alpine Linux and the musl variant of Void Linux. Just clone a mirror of public-inbox.org/meta and try and convert it:
$ git clone --mirror https://public-inbox.org/meta $ public-inbox-convert meta metanew If I pass --no-index, the process is successful. This is a deadlock of some sort, because during the hang, git cat-file is blocked on write and other things are blocked on read. That's as far as I have gotten with debugging it. -- Chris
