    Description

      The new QMap::qHash introduced in Qt 6.8 causes compilation errors because it is ambiguous:

       QMap<int,int> map;
 size_t seed = 0;
 qHash(map, seed);

      Compiler error:

      Call to 'qHash' is ambiguous
qhashfunctions.h:235:8: candidate function [with T = QMap<int, int>, $1 = true]
qmap.h:796:5: candidate function [with M = QMap<int, int>, $1 = true]
