I can confirm with patch-2.7.6, but patch-2.8 at least doesn't crash anymore:
patching file '' Hunk #1 FAILED at 125. Hunk #2 FAILED at 160. Cannot stat file , skipping backup 2 out of 2 hunks FAILED -- saving rejects to file .rej It would still be prettier to reject empty filenames. Let's see what I can do. Thanks, Andreas
