Ah! Interesting. The File System TS changes the signature of string() to return "std::string" rather than "const std::string&", and that will fix the problem.

To verify that, I first reproduced the error, and then changed the return type and verified that the problem no longer occurs. (Ubuntu Linux and clang 3.5)

I'm in process of modifying Boost filesystem to conform to the TS, and am hoping to have that ready for 1.57.

In the meantime, I'll leave the ticket open until the updated code actually ships.

Thanks for the report,
