"The memory layout of, for example, std::string isn't decided by the compiler - it's decided by the library/header files."
Not quite true. Different compilers can decide to do different alignment/padding. It should be fairly simple to make clang and MSVC avoid that scenario, though.
Also, they must have taken care to use the same ABI and C++ name mangling rules in both compilers. I would guess Microsoft's version of clang follows MSVC here, so that one can link clang code to existing third party libraries.
