Bug 175778

Compiling world with option

-stdlib=libc++ -std=c++11

or even only

-stdlib=libc++

fails building world with the below shown error message.

Obviously, libc++ is broken.

Avoiding the option -stdlib=libc++

makes buildworld run cleanly thriugh everything.

Fix: 

Avoid the build with -stdlib=libc++
How-To-Repeat: Build world with CXXFLAGS+= -stdlib=libc++ and WITH_LIBCPLUSPLUS=YES set in /etc/src.conf or /etc/make.conf
