Calling an action made by oneself crashes R3

It is not forbidden to execute MAKE for an action! value (though of course this has not much sense). Same goes for native! and op!.

However, calling the action or native one has just made crashes REBOL

>> a: make action! [[][]]
== make action! [[][]]
>> a
** crash
;; also:
>> n: make native! [[][]]
== make native! [[][]]
>> n
** crash

The error is that make action! or native! [[][]] works at all - it should throw an error.

The ACTION and NATIVE functions should be the only way to create values of these types. If the MAKE action works badly with these specs, then trial and error would eventually lead to specs that work, which would allow recreation of these functions in REBOL code when they are otherwise intentionally inaccessible. This would be a major security hole.

As it is, the behavior of the make actions of these types suggests that the resulting functions access memory badly. We are lucky that it crashes - the situation is worse for op! #1052.

For op!: see my comment in #1052.
