Hi,
I have embedded python3.3 in my application.
I got a crash when I ran a sample python script using it.
As per my assumption, On interpreter shutdown, all strings are released
(through _PyUnicode_ClearStaticStrings). (Found in one of the comments of
object.h file)
When I tried to debug python source, I found a defect in
_PyUnicode_ClearStaticStrings() method.
void
_PyUnicode_ClearStaticStrings()
{
_Py_Identifier *i;
for (i = static_strings; i; i = i->next) {
Py_DECREF(i->object);
i->object = NULL;
i->next = NULL;
}
}
Here, for loop will not free all the static strings. It will free only the
first static string in the list.
This loop needs to be corrected.
I corrected the loop in following way and its working fine for me.
void
_PyUnicode_ClearStaticStrings()
{
_Py_Identifier *i;
while(static_strings->next != NULL)
{
i = static_strings;
static_strings = static_strings->next;
Py_DECREF(i->object);
i->object = NULL;
i->next = NULL;
}
Py_DECREF(static_strings->object);
static_strings->object = NULL;
static_strings = NULL;
}
Please let me know if this is a defect or it is done so intentionally.
Please reply as soon as possible.
Thanks and Regards,
Prashant.
