@mlaurent Hm, is there a chance ABI got broken by that respective code in Qt 5.15 when it comes to the non-Qt-namespaced variants of the methods? Unless I misread, those deprecated ones are now in the QTextStreamFunctions namespace. And which might be source compatible, due to the `using namespace QTextStreamFunctions;` in the header, but does that help with the namespace being reflected in the exported symbols? Can you do some `nm -gDC /usr/lib64/libQt5Core.so.5.y.z | grep endl` (with y.z matching the actual numbers of the Qt 5.15 libs you have) and tell what exported symbols there are. by the example of `endl`?
