[Interest] tst_qatomicinteger build failure (5.9 i386/x86_64)

[Christian Gagneraud]

Hi there,

Back on my 32 bits build of Qt

I'm having a build failure on tst_qatomicinteger for qlonglong.

Static failure: Q_STATIC_ASSERT(Q_ALIGNOF(QAtomicInteger<T>) ==
Q_ALIGNOF(TypeInStruct));

Sounds very much like a 32/64 bits issue.

Any idea on what is going on?

Thanks in advance,
Chris
