No. I think you've missed the point. Neither set_error_handler() or
register_shutdown_function() report the fatal stack.
This would need to be in an extension or a mod to the core code.
Userland code can't access it.
The stack trace shown in the shutdown function is just the shutdown
function, not why there is a shutdown.
