pylint #19607 W0201 being enabled by unrelated comment [open]

Using the following versions:

pylint 0.19.0,
astng 0.19.3, common 0.46.0
Python 2.5.2 (r252:60911, Jul 22 2009, 15:33:10)
[GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu3)]

We have the following situation:

$ cat a.py
# pylint: disable-msg=W0201,W0232
class A:
  pass
$ cat b.py
import a
xa = a.A()
xa.x = 1

$ pylint -i yes --enable-checker=classes b a
$

Which is expected, the disable-msg=W0201 silenced the warning about «Attribute 'x' defined outside __init__» (and the other warning as well). Now we edit b.py to have a comment at the beginning:

$ cat b.py
#
import a
xa = a.A()
xa.x = 1
$ pylint -i yes --enable-checker=classes b a
************* Module b
W0201:  4: Attribute 'x' defined outside __init__

The addition of a simple comment in b.py has re-enabled the W0201 warning. Trying to re-disable it, e.g. via:

xa.x = 1 # pylint: disable-msg=W0201

has no effect at all. Note that the other warning (W0232) is not re-enabled by the comment, just W0201.

Also note that ordering the arguments matters:

$ pylint -i yes --enable-checker=classes a b # no output
$ pylint -i yes --enable-checker=classes b a
************* Module b
W0201:  4: Attribute 'x' defined outside __init__

I'm not familiar with the internals of pylint, so looking at ClassChecker.leave_class (the only place where W0201 is enabled) doesn't help me.
