    Description

      Methods marked as both noexcept and default (e.g. compiler generated constructors) lose the noexcept tag in documentation output if QDoc is built against Clang 18. This causes changes when compared to output from QDoc built against Clang 17 in the following files, when building documentation for a qt5.git default checkout:

      • qtcore/qitemselection.html
      • qtcore/qtcore.index
      • qtcore5compat/qstringref.html
      • qtcore5compat/qtcore5compat.index
      • qtmultimedia/qaudioformat.html
      • qtmultimedia/qtmultimedia.index
      • qttestlib/qtest.html
      • qttestlib/qtesteventlist.html
      • qttestlib/qttestlib.index
      • qtwidgets/qgraphicsgridlayout.html
      • qtwidgets/qtwidgets.index
