`sysdeps/posix/getaddrinfo.c' contains the following code:

#v+
  2033        /* Read the config file.  */
  2034        __libc_once_define (static, once);
  2035        __typeof (once) old_once = once;
  2036        __libc_once (once, gaiconf_init);
  2037        if (old_once && gaiconf_reload_flag)
  2038          gaiconf_reload ();
#v-

In the `if' statement it is assumed that `old_once' is a scalar value, which
need not be, and that it is zero-initialized by default, which need not be
either, although unlikely.


I will attach a patch with a proposal to fix this issue.
