> Windows vectored exception handler is executed with the same processor flags as in code
where exception has occurred. As Microsoft compiler generates unsafe function prolog in debug
mode, incorrect direction flag value may lead to undesirable results such as stack values
> The problem is similar to H-2010, when vectored handler changes IP address and returns
control to the OS the remaining part of handler can be executed with incorrect direction flag.
So the assembler wrappers are required to reset/restore a direction flag.
