I think there is a problem with 22.1.1, p6 which says that
-6- An instance of locale is immutable; once a facet reference is obtained from it, that reference remains usable as long as the locale value itself exists.
and 220.127.116.11, p4:
const locale& operator=(const locale& other) throw(); -4- Effects: Creates a copy of other, replacing the current value.
How can a reference to a facet obtained from a locale object remain valid after an assignment that clearly must replace all the facets in the locale object? Imagine a program such as this
std::locale loc ("de_DE"); const std::ctype<char> &r0 = std::use_facet<std::ctype<char> >(loc); loc = std::locale ("en_US"); const std::ctype<char> &r1 = std::use_facet<std::ctype<char> >(loc);
Is r0 really supposed to be preserved and destroyed only when loc goes out of scope?
