      The upstream implementation of qsort and qsort_r improves hardening against buggy comparison functions, on the code path taken after a malloc failure.

      We should consider backporting this change into Red Hat Enterprise Linux 9.

      Changes from 2.39 at least up to and including this commit should be included:
