[GoogleCodeExporter]

What steps will reproduce the problem?

1. Run the tests.
2.
3.

What is the expected output? What do you see instead?

Expected output:

Passing tests.

Actual output:

test_body, test_kwargs, and test_world all fail with the following output:

AssertionError: 0 <= index && index < m_count

What version of the product are you using? On what operating system?

pyBox2D 2.1b0 (Subversion rev. 255), Python 2.6.1, Mac OS X 10.6.2

Please provide any additional information below.

Hi,

Thank you for testing out the SVN -- it's much appreciated.

Would you mind posting the full error message, with line numbers? Please also 
let me
know your SWIG version if possible (`swig -version`).

There wasn't much of a stack trace, I grepped for the assertion and found the 
only 
match in the file "Box2D/Collision/b2Distance.h".

See below for test output and SWIG version.

Strange. I'm surprised test_joints didn't fail, as it is the only other test 
that
does a world.Step(). Perhaps the box kwarg isn't getting evaluated somehow. 

My first recommendation would be, if you had a previous build and then did `svn
update`, to clear out the 'build' directory (`setup.py clean` is not enough -- 
its
dependency checks often fail) and rebuild from scratch. 

Next, if you don't mind, try replacing test_body.py line 22:
        groundBody.CreateFixture(b2PolygonShape(box=(50,10)))
with:
        groundBody.CreateFixture(b2PolygonShape(vertices=[(0,0),(1,0),(0.5,1)]))
And see if that does anything.

If not, I'll try to look more into this tomorrow, and bug my friend to let me 
use his
Snow Leopard install. :)

Thanks for the advice.

I checked out a clean working copy and built it. I got a SWIG error so I 
upgraded SWIG to 
1.3.40 and did another clean build. All tests pass now.

Ah, good. Will have to add a note about that on the wiki at some point.

Out of curiosity, what was the SWIG error? I'm hoping to not have to require 
1.3.40
for the next release if I can.
