2.31.1, as packaged by Fedora.  b4 0.8.0 from PyPI, for what that's worth.

Specifically, I do:

  b4 am -o ~/tmp -n am -c -t 20210902220854.198850-1-corbet@lwn.net
  git am -a ~/tmp/am.mbx

...and that prints "Duplicate Signed-off-by lines." and leaves the repo
in the "in the middle of an am session" state.
