If you go to

https://travis-ci.org/boostorg/iostreams

you'll see that there are two jobs, the first one is the Linux one, with 
TOOLSET=gcc,clang - it passes. The second one is the OS X one, and it fails.

_LIBCPP_VERSION is

libc++ version 1101
    _LIBCPP_VERSION                         =1101

and clang's version is

"Clang version 7.0.2"

but I have a hunch that all Apple versions will behave in this way. Not sure 
about libc++ on other platforms such as Linux.
