                        return &internalCtor;
               }
        }
        template getClassInfo(char[] classname){
                ClassInfo getClassInfo(){
                        return cast(ClassInfo)getSymbol("__Class_").address;

                }
        }       
        mystruct getSymbol(char[] hello)
        {
                return mystruct(hello);
        }
}


notice: any grammar mistake in getClassInfo would still trigger this segfault
so i guess the problem is in the parser
