QDate causes my program to crash when I click the close button.

[need4openid]

In my class I have:

private:
    QLineEdit *edit1;
    QPushButton *button1;
    QDate date1, date2;

I do not use date1 date2 at this moment yet, I just declared them. If I comment them out, my program does not crash:

private:
    QLineEdit *edit1;
    QPushButton *button1;
    //QDate date1, date2;              // no crash

cool story

but unless you disclose more code, ideally a minimal compellable example.
Nonne will be able to help you efficiently.

I throw a generic, did you make a clean build and rerun qmake? in the mix, but that's about all I can do from the current situation.

qmake and rebuild all solved the issue! Thank you!
