This struct is passed in registers by dmd, while dmc++ (and presumably msvc) returns it on the stack, causing crash. Adding a dtor 'fixes' it. struct Prot { int kind; void *pkg; extern(D) this(int kind) { this.kind = kind; this.pkg = null; } // ~this() // { // } } extern(C++) Prot func(); void main() { auto p = func(); }
