MemoryError with parser.suite and wrong encoding declaration

[Sylvain Thenault]

Hi there !
I've noticed the following problem with python >= 2.3 (actually 2.3.4 and
2.4):

syt@musca:test$ python
Python 2.3.4 (#2, Sep 24 2004, 08:39:09)
[GCC 3.3.4 (Debian 1:3.3.4-12)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

import parser
parser.suite('# -*- coding: IBO-8859-1 -*-') Traceback (most recent call last):
File "<stdin>", line 1, in ?
MemoryError parser.suite('# -*- coding: ISO-8859-1 -*-')

<parser.st object at 0xb7e5e060>

Shouldn't parser.suite just ignore the wrong encoding declaration, or at
least raise a more appropriate exception. IMHO the first solution
would be better, since that's the behaviour of the (C) python interpreter.

Ignore the wrong declaration? All Python's that I have (on windows,
at least) raise a SyntaxError:

File "x.py", line 1
SyntaxError: 'unknown encoding: IBO-8859-1'

hum, right (with python >= 2.3 which is the first release using those
declaration...). I was sure to have checked this but I've obviously
missed something. Maybe the fact that being able to parse it anyway is
the solution I wish has driven me to write this ;) I would like this
behaviour so that pylint can check a module with a wrong encoding
declaration anyway. But at least, SyntaxError would be better than
MemoryError.
