This is just a tracking bug to investigate whether we can prevent ATF based tests to leak memory:
=================================================================

SUMMARY: AddressSanitizer: 185 byte(s) leaked in 7 allocation(s).
And this goes on and on for all ATF based tests. This prevents detecting real leaks in the unit tests.
