Don't have a full patch yet, but this is where the problem is.

clone.c, StructDeclaration::buildOpAssign().

    Parameter *param = new Parameter(STCnodtor, type, Id::p, NULL);
    Parameters *fparams = new Parameters;
    fparams->push(param);
    Type *ftype = new TypeFunction(fparams, handle, FALSE, LINKd);
#if STRUCTTHISREF
    ((TypeFunction *)ftype)->isref = 1;
#endif

    fop = new FuncDeclaration(0, 0, Id::assign, STCundefined, ftype);

+     Dsymbol *s = search_function(this, Id::assign);
+     TemplateDeclaration *td = s ? s->isTemplateDeclaration() : NULL;
+     if (td)
+     { // we need to make a template function instead
