    Archlinux + Qt 5.14.2
 
A open source project SDRAngel (https://github.com/f4exb/sdrangel) could build success on `Qt 5.9.5` & `Qt 5.9.9`.
But get compile error on `Qt 5.14.2`. (same code)
// error message:
/usr/include/qt/QtCore/qglobal.h: In instantiation of ‘T qExchange(T&, U&&) [with T = QDebug::Stream*; U = long int]’:
/usr/include/qt/QtCore/qdebug.h:118:77:   required from here

Find a solution to solve temporary. Edit /usr/include/qt/QtCore/qdebug.h line 118:
QDebug( QDebug &&other ) noexcept : stream{qExchange(other.stream, nullptr)}{}
To
QDebug( QDebug &&other ) noexcept : stream{qExchange(other.stream, (QDebug::Stream*)(nullptr))}{}
