From 21baa6e0c56d229866c02c4b42b8b53af648d853 Mon Sep 17 00:00:00 2001 From: Will Palmer Date: Wed, 14 Jul 2010 18:04:07 +0100 Subject: [PATCH] merge-tree: fix where two branches share no changes 15b4f7a (merge-tree: use ll_merge() not xdl_merge(), 2010-01-16) introduced a regression to merge-tree to cause it to segfault when merging files which existed in one branch, but not in the other or in the merge-base. This was caused by referencing entry->path at a time when entry was known to be possibly-NULL. To correct the problem, we save the path of the entry we came in with, as the path should be the same among all the stages no matter which sides are involved in the merge.
