Crash on function exit (destructor) while using QVariantList with VS2010 ?

[VS2k10_qt]

If I change the above code to this

Vector2i WzConfig::vector2i(const QString &name)
{
	Vector2i r;
	ASSERT_OR_RETURN(r, contains(name), "Missing %s", name.toUtf8().constData());
	QStringList v = value(name).toStringList();
	ASSERT(v.size() == 2, "Bad list of %s", name.toUtf8().constData());
	r.x = v[0].toInt();
	r.y = v[1].toInt();
	return r;
}

Vector2i WzConfig::vector2i(const QString &name)
{
	Vector2i r;
	ASSERT_OR_RETURN(r, contains(name), "Missing %s", name.toUtf8().constData());
	QStringList v = value(name).toStringList();
	ASSERT(v.size() == 2, "Bad list of %s", name.toUtf8().constData());
	r.x = v[0].toInt();
	r.y = v[1].toInt();
	return r;
}

To copy to clipboard, switch view to plain text mode 

Then I don't get any crashes.

So it is a problem with QVariantList for some reason.
