New submission from Damien Miller <djm at djm.net.au>:

Hi,

I just tried pypy (today head, JIT) for the first time and noticed that it compiles my py-bcrypt 
module but produces something that fails at runtime. To recreate the failure:

PYPY=/tmp/pypy/pypy/goal/pypy-c # or whatever
hg clone https://code.google.com/p/py-bcrypt/
cd py-bcrypt
$PYPY setup.py build
env PYTHONPATH=$PWD/build/lib.linux-x86_64-2.7/ $PYPY test/test.py

It looks like "s#" arguments extracted by PyArg_ParseTupleAndKeywords() are not being filled in 
correctly. For example, in py-bcrypt/bcrypt/bcrypt_python.c:bcrypt_hashpw() with a password of 
"" the corresponding password_len ends up being set to -4294967296.

I'm using Ubuntu Precise on x86_64.
