Hi Yaron

I tried your sample file out on my machine with libcxx tot and clang tot. I
should note my libcxx has some patches in that are waiting to be applied,
so it's not quite like yours, but hopefully that won't make a difference.

Your example took about 14 seconds to compile on my machine. That time is
excessive. g++ produced a similar error instantly.

I've report other excessive compile times recently and this may or may not
be related. See this bug for a similar slow example:
http://llvm.org/bugs/show_bug.cgi?id=17414

Something is definitely wrong, that something could be more than one thing.
