I have committed changes to Python 3. The compile() test now exists as test_compile.TestSpecifics.test_null_terminated.

Serhiy: You set these bugs for Python 2 as well. Is there a way to produce a non-null-terminated buffer in Python 2 to help verify this? Both John’s original array() tests and the memoryview() tests don’t seem to be supported by Python 2’s idea of buffer objects:

>>> float(array.array("B",b"A"*0x10))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: float() argument must be a string or a number
>>> float(memoryview(b"1234")[1:-1])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: float() argument must be a string or a number

I have a half-ported patch for Python 2, but it would be nice to know (a) if it is actually needed, and (b) what to do about unit tests.
