Thanks for the info. I'm still quite puzzle thought. doc.qt.io says that for Qt 5.9, the supported platform contains: Linux 32/64-bit: GCC 4.8, GCC 4.9, GCC 5.3 According to your gcc bug report, the bug was introduced in gcc 5.1 but has never been fixed (?) So if Qt supports gcc 5.3, then it supports gcc with this bug? (K)Ubuntu-17.04 ships with gcc 6.3 and Qt-5.7, surely their 32 bits OS version doesn't ship with a broken QAtomicInteger... Any clue on how I can get around this bug?
