cpython-lru_cache-weakref: Python/errors.c annotate

annotate Python/errors.c @ 13956:8e8a8df0fe73 legacy-trunk

The list comp patch checked for the second child node of the 'listmaker' node, without checking if the node actually had more than one child. It can have only one node, though: '[' test ']'. This fixes it.
