I'm using the pre-installed version of Python 2.7.12 on Ubuntu 16.04. Pretty straight forward error the following code:
PyObject * intobj = PyInt_FromLong(10);
double d1 = (double)PyLong_AsLong(intobj);
double d2 = PyLong_AsDouble(intobj);
printf("Should be the same: %f vs %f", d1, d2);
Does not display the same number for both double since `PyLong_AsDouble` raises the error, SystemError: ../Objects/longobject.c:2336: bad argument to internal function and returns -1.0 instead of 10.0.

This is incorrect use of PyLong_AsDouble(). It should be used with a long object, but you use it with an int object. |
