These tests fail on i386:

[Chuck Short (zulcss)]

This is still an issue in the master branch.

[ChangBo Guo(gcb) (glongwave)]

seems this related about arch i386 how to represent integer, need find a way to handle integer and long on Python 3.

I have no i386 machine to test, Can you try the fix as following:
