[cfe-dev] No virtual destructor in ExternalSemaSource

[Vassil Vassilev]

Hi all,
   I found out that there is no virtual destructor for ExternalSemaSource:
     include/clang/Sema/ExternalSemaSource.h:33:  ~ExternalSemaSource();
     include/clang/AST/ExternalASTSource.h:56:  virtual 
~ExternalASTSource();

   Is that bug or I am misunderstanding something? Shall we (Axel 
Naumann and me) check in patch.
Cheers,
Vassil
