I see no bug here. If you are a superuser, and create incorrect
definitions of C-level functions, you can crash the server.
Even if we thought it was useful to try to prevent incorrect definitions,
doing so would almost certainly be an unsolvable problem.
Every one of the other "bugs" you just submitted appears to also
depend on superusers doing things they should know better than to do.
It's about in the same category as complaining that "sudo rm -rf /"
crashes your system.
