[Cython] Segmentation fault with generator expressions in a cdef class (Cython 0.15.1)

[Rauli Ruohonen]

Hi,

I don't know if this has been reported yet (didn't notice a ticket
with a quick look though), but I just downloaded and installed the
latest Cython tarball and got a segfault this way:

rauli at ubuntu:~/example$ ls
bar.py  foo.pyx
rauli at ubuntu:~/example$ python bar.py
Segmentation fault
rauli at ubuntu:~/example$ cat bar.py
import pyximport; pyximport.install()
import foo

foo.Foo()
rauli at ubuntu:~/example$ cat foo.pyx
cdef class Foo(object):

   cdef object bar

   def __init__(self):
       self.bar = 'baz'
       (i for i in self.bar)
