There's an access violation, either a bug in Qt or a bug in your code (or a bug in windows). Whatever it is, you need to debug it, get a stack trace at the very least. This is your first problem. Your second problem is you're using an 8+ years old release of the library, where the last ever patch version was released ~4 years ago. You need to upgrade to Qt 5.
