[Development] qtdeclarative CI

This looks like a null pointer crash on exit.*
The main thread is processing global destructors.
The render thread is presumably trying to use an object that has already been destroyed and set to null when QApplication was destroyed. (or destroyed by a global static destructor)

It seems like the render thread needs to be shut down cleanly before / during QApplication destruction.

*The fault address of 0x8 suggests a load with offset from the null pointer.
This could be trying to access the virtual function table or the d-pointer of a class.
(I'm used to seeing 0x4 for null pointer calls to d_func() on ARM - 0x8 could be the same thing on x64)
