| Broken bytecode objects can easily crash the interpreter. |
| |
| This is not going to be fixed. It is generally agreed that there is no |
| point in writing a bytecode verifier and putting it in CPython just for |
| this. Moreover, a verifier is bound to accept only a subset of all safe |
| bytecodes, so it could lead to unnecessary breakage. |
| |
| For security purposes, "restricted" interpreters are not going to let |
| the user build or load random bytecodes anyway. Otherwise, this is a |
| "won't fix" case. |
