First of all, thanks for the tool. It looks like it will be very helpful.
I’m having a problem with global variables. The OS is Suse Linux.
The following module causes pylint to raise a recursion exception.
--- begin ---
"""This module causes 'RuntimeError: maximum recursion depth exceeded'
pylint 0.9.0,
astng 0.14.0, common 0.13.0
Python 2.3.4 (#1, Oct 5 2004, 00:26:51)
[GCC 3.3.4 (pre 3.3.5 20040809)]
"""
__revision__ = 1.0
class MyClass:
"""The name of this class does not affect the problem."""
def __init__(self, val):
self.val = val
def set(self, val):
"""Any function will cause the problem."""
self.val = val
obj = myclass(3)
def doit():
"""This function is where pylint fails.
Getting rid of the 'global' allows pylint to run to completion.
Referencing obj.val does not seem to cause a problem.
"""
global obj
obj.set(5)
# Defining obj here causes the same problem.
# obj = myclass(3)
--- end ---
Stderr (with a bunch of repeats edited out) looks like this:

Let me know if there is any other information which would be useful.
