As best I can tell, the quiet and signalling encodings will end up reversed on hppa due to the value returned by qt_qnan().
I believe the "| 0x00020000u" bit is redundant in the definition of Immediate_Mask_32. However, I don't believe the above issues are the main problem. The build log history indicates that version 5.11.3-4 was okay and 5.12.2-1 was bad. This is indicated by a segmentation fault by tst_parserstress, the first test in the testsuite. It would be nice to bisect changes between 5.11.3-4 and 5.12.2-1 to find the change that causes the problem. However, I'm not away of a suitable archive. There are also issues building 5.11.3-4 on sid: qml/qqmlmetatype.cpp: In member function 'void QQmlTypePrivate::insertEnums(const QMetaObject*) const': qml/qqmlmetatype.cpp:811:60: error: cannot convert 'const QMetaObject::SuperData* const' to 'const QMetaObject* const*' in initialization 811 | const QMetaObject * const *related = metaObject->d.relatedMetaObjects; | ~~~~~~~~~~~~~~^~~~~~~~~~~~~ ~~~~~ | | | const QMetaObject::SuperData* const There was a crashing bug patch in 5.11.3-4 that was removed in 5.12.2-1.
