--- Comment #19 from Christoph Cullmann <cullm...@kde.org> --- I compiled now the 6.1 branch locally with -DFEATURE_forkfd_pidfd=OFF That triggers (at least if I don't read the Qt sources wrongly) int ffdflags = FFD_CLOEXEC; // QTBUG-86285 #if !QT_CONFIG(forkfd_pidfd) ffdflags |= FFD_USE_FORK; #endif pid_t childPid; forkfd = ::forkfd(ffdflags , &childPid); For me, this "solves" the issues for all valgrind versions I have (Manjaro 3.16.1, vanilla 3.16.1 and 3.17.0) Naturally I assume that is not the "proper" fix. -- You are receiving this mail because: You are watching all bug changes.
