From de7a79608c94f7319b55060741d6be98826deccb Mon Sep 17 00:00:00 2001 From: Jens Lehmann Date: Sun, 31 Jan 2010 17:43:49 +0100 Subject: [PATCH] Fix memory leak in submodule.c The strbuf used in add_submodule_odb() was never released. So for every submodule - populated or not - we leaked its object directory name when using "git diff*" with the --submodule option.
