QMessageBox crashes everytime inside the function?

Everytime the QMessageBox crashes and the whole application is being crashed. Even the simple declaration also.

Code:

---

QMessageBox messbox;

---

Did you include the QMessageBox?

Code:

---

#include <QMessageBox>

---

Can you show the actual code ? I'm sure its something else, QMessageBox is working fine for thousands of Qt users ;)
Anyway, you can build the debug version, use debugger and post backtrace after crash.

I have included the header file.

and it didn't help?

I have used almost every form of QMessageBox, still it crashes everytime. In release version it works fine, but not in debug mode.

Download the newest libs from Qt.

do you have other problems in debug mode? maybe you include the release lib?

can you provide a minimal compilable program. may just with main() and messagebox inside it?
