Subject: [PULL 1/4] error: Fix "Converting to ERRP_GUARD()" doc on "valid at return"
Date: Fri, 5 Mar 2021 16:11:40 +0100 [thread overview]
Message-ID: <20210305151143.741181-2-armbru@redhat.com> (raw)
In-Reply-To: <20210305151143.741181-1-armbru@redhat.com>
Setting errp = NULL is wrong: the automatic error propagation still
propagates the dangling pointer _auto_errp_prop.local_err. We need to
set *errp = NULL to clear the dangling pointer.
