QVariant wrong cast

[A Former User]

QVariant casting does not seem to be working right. See testcase below:

 #include <QApplication>
 #include <QVariant>
 
 class CustomClass1
 {
 public: 
   CustomClass1() = default;
   int a = 0;
 };
 
 Q_DECLARE_METATYPE(CustomClass1)
 
 template <typename T>
 QVariant variantify(T &&x)
 {
   QVariant variant;
   variant.setValue(std::forward<T>(x));
   return variant;
 }
 
 int main(int argc, char *argv[])
 {
   QApplication app(argc, argv);
 
   CustomClass1 cs;
   cs.a = 1000;
   QVariant const var = variantify(cs);
   if ( var.canConvert<CustomClass1>())
     {
       CustomClass1 const cs_cast = qvariant_cast<CustomClass1>(var);
       qDebug() << "val = " << cs_cast.a; // returns 0
     }
   else
     {
       qDebug() << "conversion failed";
     }
 
   return app.exec();
 }

Expecting result: 1000.
Returned result: 0 (default initialized value)

Works for me. Which compiler and what version are you using?

@Chris-Kawa Tested with Qt 4.8.6, compiled with msvc2013

@Chris-Kawa Please disregard. Sorry. I'm a complete idiot. I had the copy and assignment ctors decorated on my local version of testcase, and it was failing because of that.
