[New-bugs-announce] [issue7065] bytes.maketrans segfaults

[egreen]

New submission from egreen <egreen at operamail.com>:

The new maketrans static method in Python 3.1 segfaults when using byte
values > 127.

Reproduce: bytes.maketrans(bytes(range(256)), b'X' * 256)

Cause: _Py_bytes_maketrans in Objects/bytes_methods.c uses signed int as
array index.

Fix attached. Also adds test.
