CentOS 7 + clang-9 + libc++:

[ RUN      ] chrono_test.locale

Check locale:

# LANG=ru_RU.UTF-8 date
Чт июн 10 16:29:03 +05 2021
# LANG=C date
Thu Jun 10 16:29:03 +05 2021

Test code:

#include <locale>
#include <ctime>
#include <sstream>
#include <iostream>

void print(const std::locale &loc)
{
    auto time = std::tm();
    time.tm_wday = 1;
    auto&& os = std::ostringstream();
    using iterator = std::ostreambuf_iterator<char>;
    const auto& facet = std::use_facet<std::time_put<char, iterator>>( loc );
    facet.put(os, os, ' ', &time, 'a', 0);
    std::cerr << "locale " << loc.name() <<": " << os.str() << std::endl;
}

int main()
{
    auto loc_c = std::locale::classic();
    auto loc = std::locale("ru_RU.UTF-8");

    print(loc_c);
    auto old = std::locale::global(loc);
    print(loc);
    print(loc_c);
    print(old);

    return 0;
}

Unexpected output:

locale C: Mon
locale ru_RU.UTF-8: Пн
locale C: Пн
locale C: Пн

After replace main function to:

int main()
{
    auto loc = std::locale("ru_RU.UTF-8");
    print(loc);
    return 0;
}

Output is:

locale ru_RU.UTF-8: Mon

glibc-2.26-lp152.26.6.1.x86_64

I don't understand why it works this way...

[vitaut]

Is it fixed by #2349?

[phprus]

Yes
