[issue9058] PyUnicodeDecodeError_Create asserts that various arguments are less than INT_MAX

[Dave Malcolm]

Dave Malcolm <dmalcolm at redhat.com> added the comment:

Patch to remove the restriction that the fields be < INT_MAX

Tested on x86_64 on a machine with > 12GB of RAM, leads to this exception, rather than the python process bailing out:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "Lib/encodings/utf_16.py", line 16, in decode
    return codecs.utf_16_decode(input, errors, True)
UnicodeDecodeError: 'utf16' codec can't decode byte 0x41 in position 2147483646: truncated data

I'm not sure about automated testing for this; the reproducer seems to need >=12GB of RAM - in borderline cases it drives my machine deep into swap, which can take a long time to recover from, and might be unacceptable in the test suite.
