simply start in debug mode and single step. line by line.
If it crashes before main function.
You have a global / static object that cause the crash. -

Well good luck .
such "drop dead" errors can be hard to find.If u can single step for looong time and no crash, then u can also
insert
QDebug() << "MARK X";
in good locations (replace X with numbers)
To give hint how far it goes before dying.
So faster locate the area of the crash. -

As mentioned running a debug version of your app under a debugger may help. Or if it's a memory corruption issue, valgrind can help.
