New submission from Dominic Lavoie <[EMAIL PROTECTED]>:
This issue is similar to issue 1229429. In the called Python method, a
regular expression fails to compile & PyEval_CallMethod() returns 0.
However, the reference count is incremented by 1 which prevents the
object from being destroyed.
Could the problem be in classobject.c, in instancemethod_call() ?
if (newarg == NULL)
return NULL;
Py_INCREF(self);
PyTuple_SET_ITEM(newarg, 0, self);
for (i = 0; i < argcount; i++) {
PyObject *v = PyTuple_GET_ITEM(arg, i);
Py_XINCREF(v);
PyTuple_SET_ITEM(newarg, i+1, v);
}
arg = newarg;
}
result = PyObject_Call((PyObject *)func, arg, kw);
Py_DECREF(arg);
return result;
}
If result is null, should Py_DECREF(self) be called in the case where
self was non-null ?
