Crashing on exiting

[duave]

Hey guys,

I was wondering what might be causing this error I'm having - basically when I put any kind of variable in my class header file it crashes the program when I exit..

Example:
My current header file contains

#ifndef TIMINGSETTINGS_H
#define TIMINGSETTINGS_H
 
#include <QDialog>
 
namespace Ui {
    class TimingSettings;
}
 
class TimingSettings : public QDialog
{
    Q_OBJECT
 
public:
    explicit TimingSettings(QWidget *parent = 0);
    ~TimingSettings();
    void AllowClearTimeChange();
 
private:
    Ui::TimingSettings *ui;
 
private slots:
    void CheckClearTime();
    void ChangePurgeTime();
    void ChangeReportingTime();
    void CheckClearCheckBox();
};
 
#endif // TIMINGSETTINGS_H

#ifndef TIMINGSETTINGS_H
#define TIMINGSETTINGS_H

#include <QDialog>

namespace Ui {
    class TimingSettings;
}

class TimingSettings : public QDialog
{
    Q_OBJECT

public:
    explicit TimingSettings(QWidget *parent = 0);
    ~TimingSettings();
    void AllowClearTimeChange();

private:
    Ui::TimingSettings *ui;

private slots:
    void CheckClearTime();
    void ChangePurgeTime();
    void ChangeReportingTime();
    void CheckClearCheckBox();
};

#endif // TIMINGSETTINGS_H

To copy to clipboard, switch view to plain text mode 

----------
It blows up on exiting if I change it like the following (adding the int testVariable):

#ifndef TIMINGSETTINGS_H
#define TIMINGSETTINGS_H
 
#include <QDialog>
 
namespace Ui {
    class TimingSettings;
}
 
class TimingSettings : public QDialog
{
    Q_OBJECT
 
public:
    explicit TimingSettings(QWidget *parent = 0);
    ~TimingSettings();
    void AllowClearTimeChange();
    int testVariable;
 
private:
    Ui::TimingSettings *ui;
 
private slots:
    void CheckClearTime();
    void ChangePurgeTime();
    void ChangeReportingTime();
    void CheckClearCheckBox();
};
 
#endif // TIMINGSETTINGS_H

#ifndef TIMINGSETTINGS_H
#define TIMINGSETTINGS_H

#include <QDialog>

namespace Ui {
    class TimingSettings;
}

class TimingSettings : public QDialog
{
    Q_OBJECT

public:
    explicit TimingSettings(QWidget *parent = 0);
    ~TimingSettings();
    void AllowClearTimeChange();
    int testVariable;

private:
    Ui::TimingSettings *ui;

private slots:
    void CheckClearTime();
    void ChangePurgeTime();
    void ChangeReportingTime();
    void CheckClearCheckBox();
};

#endif // TIMINGSETTINGS_H

To copy to clipboard, switch view to plain text mode 

Any tips on what might be causing this? I don't do anything with the variable - just the declaration alone causes the crashing..

Thanks in advance!

We can't tell from the header, show the implementation.

I'd suggest rebuilding the project from scratch. Other than that I agree with high_flyer.

Improve the question.. Add more codes

Ahh, rebuilding it fixed it - thanks wysota.
