To quote myself:

In fact when less opened I just started to scroll down until I visually
noticed an error.

The redirection seems to be an important part of it. I now did:
git ... 2>&1 | sha256sum
This gives different results basically on every run. I also noticed that
having more tags makes it easier to reproduce, so a stable kernel in contrast
to vanilla is a better trigger. Doing that without the stderr redirection gave
the same result every time I tried.
