It did not work because the signature of code object constructor was changed. Also, it used old format of bytecode (pre-wordcode).

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.
