New submission from Yannick <schmetzyann...@gmail.com>:
Python version: 3.5
Tested with VS Studio 2017 in an C-API extension.
When you have a UTF-8 encoded char buffer which is filled with a 0 or empty,
and you youse the PyUnicode_FromString() method on this buffer, you will get a
PyObject*. The content looks good, but the refence counter looks strange.
In case of an 0 as char in the buffer, the ob_refcnt Field is set to 100 and in
case of an empty buffer, the ob_refcnt Field is set to something around 9xx.
Example Code:
string s1 = u8"";
string s2 = u8"0";
PyObject *o1 = PyUnicode_FromString(s1.c_str());
//o1->ob_refcnt = 9xx
PyObject *o2 = PyUnicode_FromString(s2.c_str());
//o2->ob_refcnt = 100
I think the ob_refcnt Field should be 1 in both cases. Or why is the refcnt
here so high?
