Thank you! This is the cause:

   
https://git.savannah.gnu.org/cgit/tar.git/commit/?id=e89c7a45eba7644693870b613386baa45d624e6a

I confirmed three different ways, to convince myself. Reverting
this change on HEAD (8e548357) fixes the issue.

I did try, last week, to come up with a simpler reproducer (not
involving podman); I was unable to. I hope this is enough info.

Thanks,
E
