100% CPU load when instantiating simhash.Corpus

@dlecocq (following my twitter message).
Here are some more precise elements to diagnose the problem.

Install steps

Install package :
python setup.py install
/usr/lib/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'dependencies'
warnings.warn(msg)
running install
running build
running build_py
running build_ext
skipping 'simhash/table.cpp' Cython extension (up-to-date)
running install_lib
running install_egg_info
Removing /home/jerry/temp/simhash/lib/python2.7/site-packages/simhash-0.1.0-py2.7.egg-info
Writing /home/jerry/temp/simhash/lib/python2.7/site-packages/simhash-0.1.0-py2.7.egg-info

(I tried an install with and without a virtualenv)

package list

pip freeze
Cython==0.18
argparse==1.2.1
-e git://github.com/seomoz/simhash-py.git@1e2039d#egg=simhash-dev
wsgiref==0.1.2

Judy install without any error message

same issue here. CPU 100% and program seems dead:

>>> import simhash
>>> corpus = simhash.Corpus(6, 3)

[dlecocq]

What OS are you running this on?

[baojie]

Ubuntu 13.04 32 bit

[dlecocq]

I'm able to reproduce this in a vagrant image now. I hope to have a fix soon.

[dlecocq]

I'm sorry to report that until we migrate away from libJudy, we will be unable to support 32-bit systems. A more detailed explanation of why can be found in the commits in #7

[baojie]

I see. For the time being, I'm using a pure python implementation from https://github.com/liangsun/simhash . Wish we can switch back to this faster implementation later. Thank you.
