Description
This simple example crashes in the QtQuick Compiler Code from 6.3.0 alpha. Complete example is attached.

A C++ Model:
#ifndef SAMPLEMODEL_H #define SAMPLEMODEL_H #include <QAbstractListModel> #include <qqml.h> class SampleModel : public QAbstractListModel { Q_OBJECT QML_ELEMENT enum Roles { RoleFoo }; public: explicit SampleModel(QObject *parent = nullptr); // QAbstractItemModel interface public: int rowCount(const QModelIndex &parent) const override; QVariant data(const QModelIndex &index, int role) const override; QHash<int, QByteArray> roleNames() const override; }; #endif // SAMPLEMODEL_H
Simple Qml example that uses this model:
import QtQuick import com.mycompany.foo Window { width: 640 height: 480 visible: true title: qsTr("Hello World") SampleModel { id: sampleModel } Column { Repeater { model: sampleModel delegate: Text { required property string foo text: foo } } } }
