Dan reported a problem with the benchmark on Mac OS X:

> Hrm. On my OS X laptop: > > lir:~/Desktop/parrotbench dan$ python -O > Python 2.3 (#1, Sep 13 2003, 00:49:11) > [GCC 3.3 20030304 (Apple Computer, Inc. build 1495)] on darwin > Type "help", "copyright", "credits" or "license" for more information. > >>> import b > --> iteration 0 > --> b0 > Traceback (most recent call last): > File "", line 1, in ? > File "b.py", line 12, in ? > b0.main() > File "b0.py", line 893, in main > checkoutput(4201300315) > File "b0.py", line 763, in checkoutput > check(strhash(outputtext), n) > File "b0.py", line 3, in check > raise AssertionError("%.30r != %.30r" % (a, b)) > AssertionError: 503203581L != 4201300315L > >>>

After some off-line email exchanges I think I have a fix for this behavior, which must have to do with a different length of the addresses shown in the default repr(), e.g. "<Foo object at 0xffff>".

Version 1.0.1 of the benchmark is at the same place as before:

ftp://python.org/pub/python/parrotbench/parrotbench.tgz

(You can tell whether you have the fixed version by looking at first line of README.txt; if it says "Parrot benchmark 1.0.1" you do.)

I haven't heard back from Dan, but I assume that the fix works.

Happy New Year everyone!
