Greetings Larry !
I apologize for spamming so many people. I was hoping to get some insight into
this ! Could you let me know to whom I could reach out for help ? I've included
tehybel as I saw that he has raised/resolved some issues with PyDict in the
past.
My C code is essentially just this:
#include "Python.h"
#ifdef __cplusplus
extern "C" double test(PyObject* key, PyObject* dict)
#else
double test(PyObject* key, PyObject* dict)
#endif
{
PyObject* list = PyObject_GetItem(dict, key);
return 0.0;
}
------------
And my Python Code is this. I'm pretty sure I've got the input and output types
correct here.
from ctypes import cdll
from ctypes import *
import json
import sys
import pickle
dll = CDLL('./test2.so')
dll.test.restype = c_double
dll.test.argtypes = (py_object, py_object)
d = {68113113140: [1, 2]}
for i in d.keys():
if i == 68113113140:
break
print(dll.test(i, d)) # this works just fine
print(dll.test(68113113140, d) # this segfaults !
GDB shows me that PyObject_RichCompare (called inside PyDict_GetItem) is the
function where the segmentation fault happens !
--------
Hoping for some guidance here ! I've been trying to resolve this for 3 days
now. I have made sure that I've compiled with the correct version of Python
headers and that I'm using the same version of interpreter as well (in this
case Python 3.5.6)
