Problem with VIR_FREE() is that we are not linking libvirt-utils.so to our mock libs therefore there will be an unresolved symbol. Fortunately, nsstest that eventually links with the nssmock links also with libvirt-utils.so and thus the symbol is resolved after all. However, if one wants to run the test binary under valgrind it is impossible to do so. Because of the unresolved symbol. Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
