I don't use git-subtree, but there's some additional information which

using, what version of Git, and what shell is the shell you have as
/bin/sh (or, if you've compiled using a custom shell, the shell you're
using for that)?

Thanks for the hint. I was using ubuntu 20.04.

$ git --version
git version 2.25.1

$ bash --version
GNU bash, version 5.0.16(1)-release (x86_64-pc-linux-gnu)

To repro, you can try to split a week old version of:

https://github.com/postgres/postgres (subtree: src/interfaces/libpq)

It could take several minutes because of the size of the repo.

And then try to pull the latest version and push the merged result
into the smaller subproject.
