In locale/loadlocale.c:_nl_load_locale (line 223) if the mmap fails 'filedata' is
MAP_FAILED, but later only a possible malloc failure is checked for;
if (__builtin_expect (filedata == NULL, 0))
/* We failed to map or read the data. */
return;
That either needs to also include a MAP_FAILED check or some other way to catch
the possible mmap failure.
