Well, that's a promising start to finding the source. :)

This will all go through execv_dashed_external() in git.c. So we should
just be exiting with the status code we got from the child via wait().

You could try:

  - running it as git-send-email (with a dash), which will exec the perl
    script directly, rather than going through the main git binary

  - instrumenting run-command.c:wait_or_whine() to see how it interprets
    the value. If perl really is returning 255, then perhaps your
    platform's WIFSIGNALED() is confused by that.

If the problem does only show when going through the git binary, then I
suspect:

  git -c alias.foo='!perl -e die' foo

may be an easier reproduction.
