Never mind I can reproduce the bug with master, I probably ran 'dmd test.d' instead of './dmd test.d' after building dmd.

This version seems to compile - the new manger can't handle extern(C++) functions with D arrays as arguments or return types.

extern(C++) class A(T)
{
extern(D):
   string hi()
   {
       return "asdf";
   }
}

void main()
{
   A!string a;
}

Only the subset of extern(C++) required to interface with actual C++ code has been tested at all, so using it with D-only types is going to be fairly unpleasant.

Ok, i can understand that, but what about this one:
http://dpaste.dzfl.pl/6a9961e32e6d
It doesn't use d arrays in function interfaces. Should it work?

Similar problem, D arrays cannot be mangled correctly with C++ mangling.

This compiles:

extern(C++) interface I
{
extern(D):
   int hi();
}
   extern(C++) class A(T) : I
{
extern(D):
   override int hi()
   {
       return 0;
   }
}

void main()
{
   A!string a;
}
