- Always call ZwRaiseException in user mode and RtlDispatchException in kernel mode.
- If RtlDispatchException failed call ZwRaiseException in kernel mode. Otherwise unhandled RtlRaiseException() call in kernel mode simply ignored (do nothing)!
- Call RtlRaiseStatus in RtlRaiseException, if something went wrong.
See issue #3434 for more details.
