Thanks for reporting.
It's a known issue, don't use libstdc++ with clang. I don't know what causes it but I know more projects are affected by incompatibilities like this. Both clang+libc++ and gcc+libstdc++ work, but you have to make sure to build your entire dependency chain with only one of these libraries.
I don't don't know where the old ticket for it went, so I guess I'll link future issues here.
