| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.

* bpo-40071: Fix potential crash in _functoolsmodule.c (GH-19273)Paulo Henrique Silva2020-04-011-1/+4
| | | | | | | | | | | | | | | | | Changes on 7dd549eb0893 made _functools compatible with PEP-489 and we could have multiple modules instances loaded. But, right now there is no way to make `kwd_mark` global into a per module instance variable. kwd_mark is used on lru_cache_new which does not have a reference to a PyModule*, necessary to use PyModule_GetState. PEP-573 will solve this problem and will allow us to move the global state to per-module data and properly clear the state when unloading a module instance. This change temporarily disable cleaning of kwd_mark to avoid NULL pointer dereference if we clear kwd_mark and other module instances still alive use it.
