Bug 16525 – C++ member variables have no mangling

cat > bug.d << CODE static immutable templ(alias var) = 1234; struct D { int memvar; } extern(C++) struct CPP { int memvar; } void test() { pragma(msg, templ!(D.memvar)); pragma(msg, templ!(CPP.memvar)); pragma(msg, CPP.memvar.mangleof); // root cause } CODE dmd -c bug ---- bug.d(10): Error: variable bug.CPP.memvar Internal Compiler Error: C++ static non- __gshared non-extern variables not supported ---- Not sure if C++ defines a member variable mangling, but we need it at a couple of places and it's blocking issue 16513.
