11579	boost.log version 1.59 stream operator failure for user types	Marios Visvardis <visvardis.marios@…>	Andrey Semashev	"The following code works as expected with boost 1.57, but fails with boost 1.59:

#include <iostream>
#include <boost/log/trivial.hpp>

struct Foo
{
    int d=1;
};

std::ostream& operator<<(std::ostream& out, const Foo& foo)
{
    out << ""Foo: "" << foo.d;
    return out;
}

int main()
{
    BOOST_LOG_TRIVIAL(info) << Foo();
    return EXIT_SUCCESS;
}

I have also started a discussion in SO:

    http://stackoverflow.com/questions/32185858/problems-with-boost-log-version-1-59/32187641#32187641

and a workaround is suggested."	Bugs	closed	To Be Determined	log	Boost 1.59.0	Regression	duplicate		visvardis.marios@…
