I have a struct. The struct have a context pointer. I have this method :

The context pointer IS NOT COPIED.

Fixed it that way :

@property
auto save() inout {
     // XXX: dmd bug, context pointer isn't copied properly
     // doing it manualy using black magic.
     // Context pointer is the last element of the struct. Here in position 9.
     auto ret = inout(Lexer)(t, r.save, line, index);
     (cast(void**) &ret)[9] = (cast(void**) &this)[9];

     return ret;
}

1. We can't do anything with code snippets like that. A complete, compilable 
example is necessary.

2. Such bug reports, along with the complete example demonstrating it, needs to 
go into bugzilla, not here.
