Details:

This looks strange:

Consider this in i18.c,

get_current_locale (SCM *result)
{
  int err = 0;
  scm_t_locale c_locale;
  const char *current_locale;

(1)  c_locale = scm_gc_malloc (sizeof (* c_locale), "locale"); 


  lock_locale_mutex ();

  c_locale->category_mask = LC_ALL_MASK;
  c_locale->base_locale = SCM_UNDEFINED;

  current_locale = setlocale (LC_ALL, NULL);
  if (current_locale != NULL)
    {
 (2)     c_locale->locale_name = strdup (current_locale);
      if (c_locale->locale_name == NULL)
        err = ENOMEM;
    }
  else
    err = EINVAL;

  unlock_locale_mutex ();

  if (err)
    scm_gc_free (c_locale, sizeof (* c_locale), "locale");
  else
    SCM_NEWSMOB (*result, scm_tc16_locale_smob_type, c_locale);

  return err;
}

(1) c_locale is allocated managed by gc and not pointerless.
    e.g.  members should as well be gc allocated 
(2) a memeber of c_locale is setted to a malloced memory region
    should it be scm_strdup?
