Subject: [PATCH] qtest: do not return freed argument vector from qtest_rsp
Date: Fri, 20 Nov 2020 08:31:49 +0100	[thread overview]
Message-ID: <20201120073149.99079-1-pbonzini@redhat.com> (raw)

If expected_args is 0, qtest frees the argument vector and then returns it
nevertheless.  Coverity complains; in practice this is not an issue because
expected_args == 0 means that the caller is not interested in the argument
vector, but it would be a potential problem if somebody wanted to add
commands with optional arguments to qtest.
