[Interest] Segmentation fault on exiting Qt event loop

[Ramakanth Kesireddy]

Thanks for your mail..Yes did try with valgrind but couldn't detect memory
issue may be due to the way our app is designed using threading.
But wondering why it throws segmentation fault if qApp instance is created
on stack but not on Heap as I understand that it is mandatory to construct
qApp instance on stack by design.
