Git 2.19 Segmentation fault 11 on macOS

[ryenus <ryenus@xxxxxxxxx>]

I just updated to 2.19 via Homebrew, git range-diff seems cool, but I
only got a Segmentation fault: 11

    $ git version; git range-diff origin/master  HEAD@{2} HEAD
    git version 2.19.0
    Segmentation fault: 11

Both origin/master and my local branch each got two new commits of their own,
please correct me if this is not the expected way to use git range-diff.

FYI, I've created a sample repo here:
