EXC_BAD_ACCESS error when widget is displayed

[sparticus_37]

i have a widget that has 15 arrays of pointers to QLabels that is supposed to act as a terrain map for a simple game. each QLabel acts a as a space a player can occupy and the map is 15 x 15

mapWidget.h

class mapWidget: public QWidget
{
 
public:
    mapWidget(QWidget * parent=0);
private:
    QGridLayout * mapLayout;
    QLabel * x0[15];
    QLabel * x1[15];
    QLabel * x2[15];
    QLabel * x3[15];
    QLabel * x4[15];
    QLabel * x5[15];
    QLabel * x6[15];
    QLabel * x7[15];
    QLabel * x8[15];
    QLabel * x9[15];
    QLabel * x10[15];
    QLabel * x11[15];
    QLabel * x12[15];
    QLabel * x13[15];
    QLabel * x14[15];
    void releaseSpace(int xLoc, int yLoc);
    void occpuySpace(int xLoc, int yLoc);
};

class mapWidget: public QWidget
{

public:
    mapWidget(QWidget * parent=0);
private:
    QGridLayout * mapLayout;
    QLabel * x0[15];
    QLabel * x1[15];
    QLabel * x2[15];
    QLabel * x3[15];
    QLabel * x4[15];
    QLabel * x5[15];
    QLabel * x6[15];
    QLabel * x7[15];
    QLabel * x8[15];
    QLabel * x9[15];
    QLabel * x10[15];
    QLabel * x11[15];
    QLabel * x12[15];
    QLabel * x13[15];
    QLabel * x14[15];
    void releaseSpace(int xLoc, int yLoc);
    void occpuySpace(int xLoc, int yLoc);
};

i am adding it as a child widget to another widget frmCombat, which contains the combat options a user can have. mapWidget and frmCombat's constructors run with out errors and mapWidget is added to frmCombat.

frmCombat::frmCombat(QWidget *parent) :QWidget(parent)
{
    this->mainLayout = new QGridLayout(this);
    mainLayout->setSpacing(0);
    this->map = new mapWidget(this);
    //add map widget to frmCombat
    this->mainLayout->addWidget(map);
}

frmCombat::frmCombat(QWidget *parent) :QWidget(parent)
{
    this->mainLayout = new QGridLayout(this);
    mainLayout->setSpacing(0);
    this->map = new mapWidget(this);
    //add map widget to frmCombat
    this->mainLayout->addWidget(map);
}

To copy to clipboard, switch view to plain text mode 

however when i go and display frmCombat Mac OSX gives me a EXC_BAD_ACCESS error. is it because i am putting the QLabels in a array instead of individual QLabels?
using:
Mac OSX 10.5.8
QT 4.6
