Deadlock with "sub-logging" with clang++ on MacOSX

[yokujin]

This simple program deadlocks on line 7 (logging in function):

#define ELPP_THREAD_SAFE
#include "easylogging++.h"

INITIALIZE_EASYLOGGINGPP

std::string test() {
    LOG(INFO) << "in test";
    return "test-ret";
}

int main(int argc, char const *argv[])
{
    LOG(INFO) << "calling test: " << test();
    return 0;
}

When I remove thread safety it works, but messages are messed.

UPDATE: This happens only on Mac OS X (compiler AppleClang - Apple LLVM version 6.0 (clang-600.0.56)). Same program compiled on Linux (compiler GNU 4.9.1) works as expected.
