More than likely. It does appear libc++ does not go through same pains
to maintain ABI stable as libstdc++ does. The lack of all and any
symbol versions in shared library binary strongly suggests that not
only they do not bother with ABI stability, they simply can't enforce
it at the moment even if they wanted to.
