Not really.

Q_ASSERT, if it fails, calls qt_assert, which will abort the application with 
a core dump (SIGABRT) or, on Windows, call the debugger routines indicating 

Q_ASSERTs are not survivable. If you trip one, the application terminates.

Q_CHECK_PTR only checks for null. It can't tell an invalid pointer from a 
valid one.
