In Qt 4.7.0-beta1 the assignment operator for QVarLengthArray has a wrong behaviour, it appends instead of replacing the data. It was working OK in previous Qt versions as far as I can tell.
Example code (attached as qmake project):
#include <QtCore/QCoreApplication>
#include <QVarLengthArray>
#include <QDebug>
struct A
{
A() : a(false) {;}
bool a;
};
int main(int , char *[])
{
QVarLengthArray<A,8 > sides1;
sides1.resize(6);
QVarLengthArray<A,8 > sides2;
sides2.resize(7);
sides2 = sides1;
qDebug() << sides1.size() << sides2.size();
Q_ASSERT(sides1.size()==sides2.size());
// Output: 6 13
}
