Hi,
Running sympy's test suite would be a good test for pypy. Sympy is a
python module for symbolic mathematics (www.sympy.org). The release
0.7.2 is being prepared and there is a single test failure remaining
when running under pypy nightly (from a couple days ago). It boils
down to this small example:
dirac:~/git/sympy $ cat test_arnault.py
from sympy.ntheory import isprime
# Arnault's number
a = int('''
803837457453639491257079614341942108138837688287558145837488917522297\

Python 2.7.3 (7f6d5c878b908afec8a643b6d6166dfbd0af2bdf, Oct 03 2012, 11:42:40)
[PyPy 1.9.1-dev0 with GCC 4.6.2]
This code (isprime) is part of previous sympy releases, and this
failure did not happen with pypy 1.9 but happens with the nightly from
Oct 3 (self built with translate.py -Ojit). Can anyone reproduce?
Thanks,
Cheers,
Julien
