On gcc/x86, when a class or struct has a copy constructor or destructor and is passed by value to a function, the caller creates a temporary copy and passes a pointer to the copy. LLVM does the same. msvc++ does not use the pointer trick. It puts the class on the stack like any other function parameter. How to pass a class parameter `byval' while honoring the copy constructor and/or destructor? -- Óscar
