A strange crash occurring with QList copy assignment operator

[HFT_developer]

Hi,

I am coming across a strange crash in Qt when I use the copy assignment operator of the QList. Code below:

// class 1

    // parse and store the input data into the member variables
    m_numerator   = parseInputData(_numerator);
    m_denominator = parseInputData(_denominator);


    m_divisor->setParameters(m_numerator, m_denominator, checkCoeff(_numerator), std::max(numPower, denPower));


// Inside m_divisor's class :
void Divisor::setParameters(const QList<double> &numerator, const QList<double> &denominator, QChar coeff, int maxPower)
{
    m_Dnumerator  =numerator; // app is crashing here but why?
    m_Ddenominator=denominator;
    m_Dcoeff      =coeff;
    m_DmaxPower   =maxPower;
}

Please give advice.

Start your app in debug mode and look at the stack trace (left down panel)
