Can you copy-and-paste the exact commands you are using to build and run the benchmarks (along with version info for the interpreter used to do the building) as I'm on the same revision and can't reproduce anymore?

$ mkdir benchmarks_py3k
$ cd benchmarks_py3k/
$ $ /usr/bin/python2.6 -V
Python 2.6.5
$ PYTHON=/usr/bin/python2.6 ../benchmarks/make_perf3.sh ../benchmarks
# ... 2to3 output
$ python3 -V
Python 3.2.3
$ python3 perf.py -f -b 2to3 `which python3` `which python3`
