Dumpcpp creates a QVariant& function without initialising the QVariant

I've used dumpcpp to create a .h and .cpp file for Microsoft Word: word.h and word.cpp

Building the program gives two errors (same errors):
c:/.../word.h:65535: error: 'qax_result' : references must be initialized

The generated code is:
inline QVariant& _Document::SetActiveWritingStyle(QVariant& LanguageID, const QString& rhs)
{
QVariant& qax_result;
void *_a[] =

{(void*)&qax_result, (void*)&LanguageID, (void*)&rhs};
qt_metacall(QMetaObject::InvokeMetaMethod, 259, _a);
return qax_result;
}

A screenshot is attached.

To build my program I have currently solved the problem like this:
inline QVariant& _Document::SetActiveWritingStyle(QVariant& LanguageID, const QString& rhs)
{
QVariant *v = new QVariant();
QVariant& qax_result = *v;
void *_a[] = {(void*)&qax_result, (void*)&LanguageID, (void*)&rhs}

;
qt_metacall(QMetaObject::InvokeMetaMethod, 259, _a);
return qax_result;
}
