Compilation output containing the error
Clang is incompatible with some uses of std::tuple using the visual studio STL.
More specifically, when inheriting from it.
struct Foo : private std::tuple<int> {
void bar() {
std::get<0>(*this) = 1;
}
};
int main() {
Foo f;
f.bar();
}
The code above compiles perfectly using GCC (libstdc++), Clang on linux
(libstdc++), and MSVC (using it's own STL).
The mix of clang and MSVC's STL result the compilation error sent as
attachement.</pre>
