generic catch-all error during runtime

[babygal]

I am getting runtime error as in attachment.
Code :

QDoubleSpinBox *AspinBox,*BspinBox,*CspinBox,*DspinBox;
func( float&,float&,float&,float&);
float a,b,c,d;
 
AspinBox= new QDoubleSpinBox;
BspinBox= new QDoubleSpinBox;
CspinBox= new QDoubleSpinBox;
DspinBox= new QDoubleSpinBox;
 
a = AspinBox->cleanText().toFloat();
b = BspinBox->cleanText().toFloat();
c = CspinBox->cleanText().toFloat();
d = DspinBox->cleanText().toFloat();
 
QString strA = QString::number( a );
QMessageBox::about(this,tr("ED apical trim in mm #"),strA );  //value read back is correct
func(a, b, c, d);    //I  guess this function is causing error

QDoubleSpinBox *AspinBox,*BspinBox,*CspinBox,*DspinBox;
func( float&,float&,float&,float&);
float a,b,c,d;

AspinBox= new QDoubleSpinBox;
BspinBox= new QDoubleSpinBox;
CspinBox= new QDoubleSpinBox;
DspinBox= new QDoubleSpinBox;

a = AspinBox->cleanText().toFloat();
b = BspinBox->cleanText().toFloat();
c = CspinBox->cleanText().toFloat();
d = DspinBox->cleanText().toFloat();

QString strA = QString::number( a );
QMessageBox::about(this,tr("ED apical trim in mm #"),strA );  //value read back is correct
func(a, b, c, d);    //I  guess this function is causing error
