See the following code : https://github.com/gchatelet/dlang_cpp_std/blob/0ff5abaf035a352dd3b46d5b19b2cd222cedf7a6/cpp_std.d The constructor is mangled as : std::basic_string<char, std::char_traits<char>, std::allocator<char> >::__ctor() But should be defined as : std::basic_string<char, std::char_traits<char>, std::allocator<char> >::basic_string() Same thing for the destructor.

Constructors and destructors are intentionally not mangled correctly, as they do not match the expected C++ abi in other ways. While this might be made to work in the future it's an intentional limitation and not a bug.

I use pragma(mangle) to force the mangle for ctors to link to C++ ctor's just fine... in what way is the ABI incompatible?
