Really? How do you cope in CI? You don't build for linux-32 anymore?

Scary, i then cannot run the tests about Qt's atomic integer solutions!

Does QAtomicInteger<quint64> works safely with Qt 5.6 on a linux 32
bits box with gcc > 5.1?

Should i use QAtomicInteger<quint64> on 64bits and
QAtomicInteger<quint32> on 32 bits?

If you or I cannot build and so cannot run QAtomicInteger's test
suites, then how do you or how do I know it works as adverstised?

Thanks,
Chris
