Opencv program exited with code -1073741819

I am working on a video processing project using opencv and QT. Every bit of code runs perfect but when I close the GUI of my application its shows stopped working error in Windows 7:

  Problem Event Name:   APPCRASH
  Application Name: QtTracker3.exe
  Application Version:  0.0.0.0

  Exception Code:   c0000005
  Exception Offset: 00052016

  Additional Information 3: 0a9e
  Additional Information 4: 0a9e372d3b4ad19135b953a78882e789

and debugger gives:

HEAP[QtTracker3.exe]:

I cant figure out why this happens...:-(

c0000005 is an access violation error, a common reason is that you might try to access something that was already de-allocated (based on the information that it happens on application exit) though a invalid pointer.

Also a common mistake with Qt is to have child widgets allocated on stack and if the parent widget is destroyed first it calls delete on child address (a address that isn't allocated on heap and that can cause the error too), but basically you have to debug your program to find the bug.
