When you store the current locale information, the program could 
potentially run out of memory. You have to check that, which StatistX 
does by testing the condition
   SX_saved_locale == NULL
If this condition is true, the program has no memory left (or something 
else went wrong). statist should perform the same test at the same place 
and handle the problem in some way. E.g. the following is a possible way 
to deal with it:

if (saved_locale == NULL) {
    /* Run out of memory. Fatal, stop the program. */
    out_err(FAT, ERR_FILE, ERR_LINE,
          _("set locale: Not enough memory."));
}


Look at "statist.h" for details about out_err(). If possible, one could 
also use mymalloc() from memory_handling.h.
