From e336bdc5b9bcb62982da9708dfb6e68150de72a3 Mon Sep 17 00:00:00 2001 From: Kevin Willford Date: Mon, 28 Aug 2017 14:28:27 -0600 Subject: [PATCH] merge-recursive: fix memory leak In merge_trees if process_renames or process_entry returns less than zero, the method will just return and not free re_merge, re_head, or entries. This change cleans up the allocated variables before returning to the caller.
