The following extension module crashes when passed a non-string argument rather
than throwing a TypeError:
************* string_bug.pyx *****************
from libcpp.string cimport string
cdef extern from "stdio.h":
int printf(char *format, ...) nogil
def blow_up(string text):
printf(text.c_str())
*****************************************
To see this run
************* show_bug.py *****************
import string_bug
# This is O.K.
string_bug.blow_up("Testing...")
# This seg faults for me.
string_bug.blow_up(1)
*****************************************
Here is my setup.py for your convenience:
************** setup.py *******************
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
setup(cmdclass={'build_ext': build_ext},
ext_modules=[Extension("string_bug",
sources=["string_bug.pyx"],
language="c++")])
******************************************
Also, I have:
> python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import Cython
>>> Cython.__version__
'0.19.1'
Cheers,
