Cannot compile 1.72.0 on Windows using Visual Studio 2019 with /std:c++latest #747

The source of boost library is acquired from https://www.boost.org/users/history/version_1_72_0.html .

As the title indicates, compilation fails on boost 1.72.0 while 1.71.0 works fine with /std:c++latest on Visual Studio 2019. And /std:c++17 works fine too.

Not sure this is a bug with Visual Studio or boost library. I opened an issue for Visual Studio team, too.

This issue was moved by chriskohlhoff from boostorg/asio#325.

The error is definitely reproducible. Another coworker of mine also faces the same issue.

I found a minimal reproducible case:

#include <boost/asio.hpp>

int main() {
    return 0;
}

Compiling this with /std:c++latest gives:

This might be a duplicate of #312

I experienced the exact same problem and confirm that boost 1.72.0 w/ VS-2019 compiled fine when the language flag is set to /std:c++17 but failed when set to /std:c++latest
