MacOS hasn't shipped with gcc for a while now. If you were serious about using
gcc & its STL implementation you would install your own copies of the tools &
libraries. So what's on the

I tried it out on OSX and the problem is that version of libstdc++ shipping
with every recent OSX version (don't know about old ones) is 4.2.1 (last
version with GPL v2) what doesn't support std::unique_ptr (supported since
4.3). Because of this I think the correct
tberghammer added a comment.
My understanding (don't have an OSX machine at hand right now to try out) is
that OSX ships with the libstdc++ belonging to gcc-4.2.1 and that version of
libstdc++ is too old to support c++11 features such as std::unique_ptr.
Regarding skipping tests I am not aware

There's no reason you couldn't build the gnu libstdc++ on Darwin. Anyway, if
that's the problem, I'm pretty sure the testsuite has a way to conditionalize
on which stdlib(s) are available. That would be clearer than conditionalizing
on platform.

This test compiles correctly on Darwin if you pass the --std=c++11 flag.
lldbtest has a getstdFlag that returns the correct std value in this case. Can
you get the test running
