I think it is eitehr bug in source (LLVM). Most probably becuase libLLVMAsmParser simply omits inline definition in libLLVMAsmParser.so where it should not or some sort of bug in C++ visibility logic. For that we need to figure out how the symbol is defined and used in lib/libLLVMAsmParser.so Honza
