Subject: [PATCH v3 4/4] restore_env(): free the saved environment variable once we are done
Date: Tue, 02 Feb 2016 15:50:02 -0800 [thread overview]
Message-ID: <xmqqio26pt91.fsf_-_@gitster.mtv.corp.google.com> (raw)
In-Reply-To: <xmqqy4ba627n.fsf_-_@gitster.mtv.corp.google.com> (Junio C. Hamano's message of "Wed, 27 Jan 2016 15:18:36 -0800")
Just like we free orig_cwd, which is the value of the original
working directory saved in save_env_before_alias(), once we are
done with it, the contents of orig_env[] array, saved in the
save_env_before_alias() function should be freed; otherwise,
the second and subsequent calls to save/restore pair will leak
the memory allocated in save_env_before_alias().
