This looks really like a bug in MSVC. If you remove the virtual in

    virtual void DeleteExpr(ExprTy *E) {}
    virtual void DeleteStmt(StmtTy *S) {}
    virtual void DeleteTemplateParams(TemplateParamsTy *P) {}

the bug goes away. However this is not an option. I've attached a really 
ugly workaround (please, please don't blame me, it is not meant to get 
checked in). If you remove the c-style-cast in the get function the 
compiler tells you to a certain degree what's going on internally. It 
looks like MSVC doesn't have the right template argument and instead 
selects some random name. Thus I'm not even sure if MSVC generates 
working code at all.
