>Description:
[src/libexec/ftpd/cmds.c:651]: (error) Dead pointer usage. Pointer 'pdir' is dead if it has been assigned '&dir' at line 647.

           if (stat(realdir, &dir) == 0)
                pdir = &dir;
        }
    }
    pdirwok = 0;
    if (pdir != NULL) {

but dir is local only to the previous block:

        struct stat dir;
