--- Comment #3 from Michael Stefaniuc mstefani@redhat.com --- Ok, I think I know where the other comes from: create_dswave() was leaking memory on CoCreateInstance failure aka when the test was requesting an unsupported IID. That was fixed in the same series but in the previous patch aka 5843a1a00207e25959d35d3f94e2cfe89d2d6af2.
