Comment (by jeremyhu@…):

 r131410 for the `__builtin_unreachable()` bug.  Also see
 http://www.llvm.org/bugs/show_bug.cgi?id=22198

 I'm able to reproduce some of this by editing the port to force 97.17 on
 Yosemite and building like:

 {{{
 sudo port -v -s destroot ld64 -universal cxx_stdlib=libstdc++
 }}}

 I'll try to address these build errors and see how much that helps you.
