 2Broken bytecode objects can easily crash the interpreter.

 4This is not going to be fixed.  It is generally agreed that there is no
 5point in writing a bytecode verifier and putting it in CPython just for
 6this.  Moreover, a verifier is bound to accept only a subset of all safe
 7bytecodes, so it could lead to unnecessary breakage.

 9For security purposes, "restricted" interpreters are not going to let
10the user build or load random bytecodes anyway.  Otherwise, this is a
11"won't fix" case.
