            Bug ID: 28746
           Summary: _FORTIFY_SOURCE does not work for stpcpy
           Product: glibc
           Version: 2.35
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: siddhesh at sourceware dot org
          Reporter: siddhesh at sourceware dot org
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

The definition for the fortified version of stpcpy and a few other functions
are incorrectly under __USE_GNU when they should be under __USE_XOPEN2K8
because of which, they don't get fortified when _GNU_SOURCE is not defined.
