> ./configure --enable-pystats --with-pydebug > make -j ... _bootstrap_python: ../../cpython/Include/object.h:215: Py_SIZE: Assertion `ob->ob_type != &PyLong_Type' failed. 

It looks like #102464 missed removing this use of Py_SIZE on a PyLongObject because it is gated behind #ifdef Py_STATS.

When debug is enabled, this causes an assertion to fail. Without assertions, I think it can cause inaccurate stats collection for STORE_SUBSCR specialization failures.
