[Bug c++/27370] [4.0 Regression] Bogus warning about ignoring function return value (__attribute__ ((warn_unused_result)))

[rguenth at gcc dot gnu dot org]

------- Comment #2 from rguenth at gcc dot gnu dot org  2006-05-01 15:24 -------
Though 4.1.0 seems to not warn at all:

class QByteArray {
public:
  QByteArray(const QByteArray &);
};
class QString {
  QByteArray toLocal8Bit() const __attribute__ ((warn_unused_result));
  inline QByteArray local8Bit() const{ return toLocal8Bit(); }
  void fooWarnHere() const { toLocal8Bit(); }
};

should warn for fooWarnHere, but doesn't.
