I think I fixed this semi-independently last week; see the thread at:

  
http://public-inbox.org/git/20161006164723.ocg2nbgtulpjc...@sigill.intra.peff.net/

I say semi-independently because I didn't actually know about your
previous report, but saw it in the wild myself. But I did talk with
Michael off-list, and he suggested the belt-and-suspenders retry counter
in my second patch.

The fix is at e8c42cb in Junio's tree, and it's currently merged to
'next'.
