Here below is my code of VisitStmt() and VisitLabelStmt(), I know when to
return true//false from visitor method and I have tried
VisitLabelStmt(LabelStmt* s) and VisitLabelDecl(LabelDecl* d) too. No luck. 

bool MyProcessStmtBox::VisitStmt(Stmt *s)
  clang::SourceManager & sm = this->m_compilerInstance->getSourceManager();
  clang::SourceLocation locStart = s->getLocStart();

  std::cerr << "\n found stmt \n";
  std::cerr << "\t" << stmtToStr(s) << " at ";
  std::cerr << "\n";
  std::cerr << "StmtClassName = " << s->getStmtClassName();

  if (strcmp(s->getStmtClassName(), "LabelStmt") == 0)
      std::cerr << "\n found LabelStmt\n";
  // Returning false from one of the overridden visitor functions
  // will abort the entire traversal.
  return true;

bool MyProcessStmtBox::VisitLabelStmt(Stmt* s)
  std::cerr << "\tLabelStmt: \n";
  s->dump(); // TODO: remove

  return false;
