Thanks, but it does not reproduce with the above procedure. Following the above (with $repo_name set to "trash" that is not a name of any existing directory in the current directory, and $repo_url set to a local repository that exists but without any history), I got the "Add file01.txt" from the last step.

I got

    No refs in common and none specified; doing nothing.
    Perhaps you should specify a branch.
    fatal: the remote end hung up unexpectedly
    error: failed to push some refs to '/var/tmp/x/./empty.git'

after both of "git push", but becuase "git log" that does not say where to start cares only about HEAD, in the above reproduction precipe "git push" should be irrelevant (i.e., if your copy of Git is broken to exhibit the above reported bug, it should show the same symptom without these steps to run "git push").

If there are some hooks that modifies the history after your "git push", it would be a different story, but otherwise I am not sure how any version of Git would exhibit such a symptom.

Puzzled.
