[New-bugs-announce] [issue26421] string_richcompare invalid check Py_NotImplemented

[yuriy_levchenko]

New submission from yuriy_levchenko:

i have object with flag Py_TPFLAGS_STRING_SUBCLASS

stringobject.c (line 1192) in function string_richcompare

we have check string PyString_Check

but,

#define PyString_Check(op) \
                 PyType_FastSubclass(Py_TYPE(op), Py_TPFLAGS_STRING_SUBCLASS)

i successful check this. But my type is not PyStringObject

Maybe need replace this check on PyString_CheckExact?
