--- Comment #11 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > Further support from valgrind on x86_64-pc-linux-gnu: I was not questioning the PR, but the regression: if I don't see the leak at 4.9 on my builds, there is a suspicion that the bug may have been latent and only exposed by a recent change.
