[issue14373] C implementation of functools.lru_cache

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

The problem is in property descriptor getter. It uses cached tuple for args and can unexpectedly modify it. Opened issue24276 for fixing this bug.

Another way is to remove fast path in lru_cache_make_key() and always copy args tuple.
