This line of code has been in the library forever and never given us
any trouble, but now that I look at it closely I'm not sure you are
allowed to compare two streams for equality like this. Can you try
changing that line of code to:
if (os.rdbuf() == std::cout.rdbuf())
instead, and see if your compiler likes that any better?
