A few details might be relevant here. The directory searched for some of
C/C++ standard headers (libstdc++) is wrong for i386/i686 (it should
search /usr/include/c++/4.8 and /usr/include/i386-linux-gnu/c++/4.8);
(1) /usr/include/c++/4.8 is searched
(2) /usr/include/i386-linux-gnu/c++/4.8 is __NOT__ searched
A workaround is to add an additional include search path (if you are using 4.8)
when compiling with clang++:
-I/usr/include/i386-linux-gnu/c++/4.8
----------------------------------------------------------
the warning below during the compile command (highlights the problem):
ignoring nonexistent directory
"/usr/lib/gcc/i686-linux-gnu/4.8/../../../../include/i686-linux-gnu/c++/4.8"
----------------------------------------------------------
