### 3634. When are static-duration `memory_resource` objects destroyed?

Section: 20.12.4 [mem.res.global], 19.5.3.5 [syserr.errcat.objects] Status: New Submitter: Jiang An Opened: 2021-11-07 Last modified: 2022-01-29

Discussion:

Both `std::pmr::new_delete_resource` and `std::pmr::null_memory_resource` return pointers to static-duration objects. It seems unspecified when the pointed-to objects are destroyed, so users can't reliably use these objects during destructions of their static-duration objects.

`std::generic_category` and `std::system_category` have the same issue, except that the referred-to objects may have different storage duration.

Should we specify in which case can these objects be used in the termination of a program?
