glibc/intl/finddomain.c
Ulrich Drepper f84ad0b1e0 Update.
* intl/finddomain.c (free_mem): Also free filename.
	* locale/findlocale.c (free_mem): Likewise.
	(_nl_find_locale): Duplicate loc_name with strdupa not strdup.
	* locale/setlocale.c (free_mem): New function.  Free current locale
	data and set current locale to "C".
