--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Confirmed from 5.4 up to trunk. The change occurred between revisions r232451 +
1 patch (2016-01-15, OK) and r233563 + 2 patches (2016-02-19, pointer being
freed was not allocated). AFAICT one of the patch is for pr69423 (r233589) and
the second for pr67451 (r233625), but I cannot see why it can cause the
problem.
