I'm getting a weird segfault from a tiny function (SSCCE) using cython
with python 2.7.  I'm seeing something similar with cython and python
3.5, though I did not create an SSCCE for 3.5.

This same code used to work with slightly older cythons and pythons,
and a slightly older version of Linux Mint.

The code is at http://stromberg.dnsalias.org/svn/why-is-python-slow/trunk
(more specifically at
http://stromberg.dnsalias.org/svn/why-is-python-slow/trunk/tst.pyx )

In short, cdef'ing a list of doubles with about a million elements,
and using only the 0th element once, segfaults - but cdef'ing a
slightly smaller array does not segfault under otherwise identical
conditions.

Any suggestions?  Does Cython have a limit on the max size of a stack frame?

Thanks!  I quite like cython.
