Yes, this works for me in the latest (unstable) developer branch, but fails
in the release branch:
$ cd cython-unstable
$ cat rangeloop.pyx
def func():
for (a, b) ,c ,d in zip(zip(range(3), range(3)), range(3), range(3)):
print a, b
print c
print d # This line segfault
$ python2.6 -c 'import pyximport; pyximport.install(); \
import rangeloop; rangeloop.func()'

$ cd ../cython-release

import rangeloop; rangeloop.func()'

Not sure why. I'm moving this to the Cython mailing list, we should be able
to help you there.
