Qt Application crashes and no clues to understand cause of the crash...

[Hetal]

Our application crashes multiple times and showing following call stack:

qt5core!QCoreApplication::notifyInternal2+0x88
qt5core!QEventDispatcherWin32Private::sendTimerEvent+0xfc
qt5core!QEventDispatcherWin32::processEvents+0xe54
user32!UserCallWinProcCheckWow+0x1fc
user32!DispatchMessageWorker+0x1a7
qt5core!QEventDispatcherWin32::processEvents+0x536
qt5core!QEventLoop::exec+0x1b3
qt5core!QThread::exec+0x92
qt5core!QThread::start+0x331
kernel32!BaseThreadInitThunk+0x22
ntdll!RtlUserThreadStart+0x34

We have these kind of crashes many times, is there a way to identify cause of these issues?
Also, is there any way to understand the Qt Signal - Slot call stack, so that we can reduce no of crashes in our application.

Thanks,
Hetal

Have you rerun qmake and rebuilt of whole application?

After checks above you need to make sure that you are compiling in debug mode and use the debugger. With the debugger you can set break points and see how far you can get without crash.
