Comment 1 Sergei Trofimovich (RETIRED) gentoo-dev

Did you by chance use different gcc versions to compile llvm and include-what-you-use?

gcc-4.8/9 to gcc-5.x changed c++ ABI for some stdlib types.

In this case rebuilding sys-devel/llvm and sys-devel/clang with your current gcc should help.

Comment 2 Nado 2016-10-04 16:26:50 UTC

Indeed that was the cause.
Thank you for your time.
