i am trying to execute QT Application on Window NT 4.0 Platform .
This Application is statically Compiled with QT 4.5.3. Problem which i am facing is that Debug build is running sucessfully on win NT 4.0 but whenever i tried to execute Release build of the same application, this application crashed with illegal instruction error.
Later after trying different option i came to know that its failing in Qwidget->show() method.

Same Release build is executing on other platforms(windows 2000, Xp )

It would be very kind if some can help me to solve this issue.
