From 03b69c7606267bc978c69cf88fcd7a8edf8175bc Mon Sep 17 00:00:00 2001 From: Mike Hommey Date: Tue, 11 Dec 2007 22:59:55 +0100 Subject: [PATCH] Fix small memory leaks induced by diff_tree_setup_paths Run diff_tree_release_paths in the appropriate places, and add a test to avoid NULL dereference. Better safe than sorry.
