Description

As discussed in this thread, when compiled as 64 bit with Sun Studio C++ 12 on Solaris 10u5 AMD64,
the program below crashes on some systems:

#include <locale>
#include <string>

int main() {
    std::locale loc = std::locale("fr_FR");
    std::string s1("Et la marine va venir à Malte");
    std::string s2("Et la marine va venir à Malte");
    const std::collate<std::string::value_type>& col =
        std::use_facet<std::collate<std::string::value_type> >(loc);
    if (col.compare(s1.c_str(), s1.c_str() + s1.length(),
                    s2.c_str(), s2.c_str() + s2.length()) == 0)
        return 1;
    return 0;
}
