Are some compiler messages missing in the above quote? It feels like the above line is not directly related to the lines below, but perhaps I am misinterpreting the messy output. > I'm puzzled: I wouldn't expect this to be an OS-specific failure. We cannot be sure it is OS-specific, but STL implementation is full of hacks and optimizations that may be OS- or environment-specific. It is also possible that there is a conflict between GCC and clang installation; we have seen those before and they manifest in weird ways. It is strange that the error below mentions "unordered_map" when it should say "std::unordered_map" or similar. Are you building with clang standard library or GCC standard library (I believe -stdlib controls that, but it is not my area of expertise)? If you are building with GCC stdlib, perhaps try building with clang-provided stdlib?
