Assertion failure in _imp.get_frozen_object if data object contains bad marshal data

[chgnrdv]

Repro:

import _imp
>>> _imp.get_frozen_object('x', b"6\'\xd5Cu\x12")

Output:

python: Objects/object.c:541: PyObject_Repr: Assertion `!_PyErr_Occurred(tstate)' failed.
Aborted (core dumped)

I'll submit a PR.

When is get_frozen_object called with a data argument? On PyPy we do not have a data argument to the function and everything seems to work well.
