From dc7090efbc8280e482a6b2dc7419e525cbc3c5d7 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sun, 12 Jun 2005 17:23:15 -0700 Subject: [PATCH] [PATCH] Re-Fix SIGSEGV on unmerged files in git-diff-files -p When an unmerged path was fed via diff_unmerged() into diffcore, it eventually called run_diff() with "one" and "two" parameters with NULL, but run_diff() was not written carefully enough to notice this situation.
