1""" 2Broken bytecode objects can easily crash the interpreter. 3 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. 8 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. 12 13""" 14 15import types 16 17co = types.CodeType(0, 0, 0, 0, 0, b'\x04\x71\x00\x00', 18 (), (), (), '', '', 1, b'') 19exec(co) 20
