[Bug c++/17109] New: bogus syntax error of c++ 3.4.0 triggered by -O

["krelisnet at softhome dot net" <gcc-bugzilla@gcc.gnu.org>]

The code below results in syntax error when using -O. The syntax error is not
mentioned when omitting -O.

test.cc:
#-----------------------------------------------------
#include <string>

enum keyword_type {UNKNOWN = -1, TEXT, DATE, NUM};

class keyword {
public:
  keyword () {type = UNKNOWN; }
  
  std::string gettext() 
    { 
      return txt;
    }
private:
  enum keyword_type type;
  std::string txt;

};

#-----------------------------------------------------

invocation:
g++34 -v -save-temps -c -O test.cc

#-----------------------------------------------------
