[Bug c++/27371] New: [4.1/4.2 Regression] Does not warn about unused function result (__attribute__((warn_unused_result)))

[rguenth at gcc dot gnu dot org]

class QByteArray {
public:
  QByteArray(const QByteArray &);
};
class QString {
  QByteArray toLocal8Bit() const __attribute__ ((warn_unused_result));
  void fooWarnHere() const { toLocal8Bit(); }
};

Does not complain about fooWarnHere().  4.0.3 did this.
