[3.7] bpo-40412: Nullify inittab_copy during finalization (GH-19746) by miss-islington · Pull Request #19842 · python/cpython
Otherwise we leave a dangling pointer to free'd memory. If we
then initialize a new interpreter in the same process and call
PyImport_ExtendInittab, we will (likely) crash when calling
PyMem_RawRealloc(inittab_copy, ...) since the pointer address
is bogus.
