Yes, it's a Clang bug. See https://bugs.llvm.org/show_bug.cgi?id=33518.

We're working with them to figure out what the proper solution should be. You 
can work around this problem now by deleteing these lines from 
qcompilerdetection.h:

#if QT_HAS_CPP_ATTRIBUTE(nodiscard)         // P0188R1
#  undef Q_REQUIRED_RESULT
#  define Q_REQUIRED_RESULT [[nodiscard]]
#endif
