You are creating a 10 level nested structure of iterators. It is no wonder
that you exhaust the stack space of the interpreter. You would get the same
with any iterator combination, nothing special with zip and starmap here.

Kristján, we already have provisions to avoid stack overflows, instead bailing
out with a RuntimeError. So this is a bug.

I got no response for about 10 secs until a process restart happens, which I
believe means that the background pythonw process stopped.
If I hit ^C before that, I get

New submission from Per Myren progr...@gmail.com:
The following code crashes with a segfault on Python 2.7.2:
from operator import add
from itertools import izip, starmap
a = b = [1]
for i in xrange(10):
a = starmap(add, izip(a, b))
list(a)
It also crashes with Python 3.2.2:

Apparently it's a stack overflow between zip_next and starmap_next.
