It looks like Travis recently upgraded to a clang with a (better) LeakSanitizer. The following tests have memory leaks: * shared-random/vote * shared-random/sr_compute_srv * shared-random/state_transition They are missing a call to sr_state_free() in 0.2.9 and later. But it's spelt sr_state_free_all() in 0.3.3 and later.
