[Bug c++/30019] New: g++ did not issue a warning when it (IMO) could have

[dflogeras2 at gmail dot com]

Hi, I mixed up the following code to reset a ostringstream

ostringstream oss;
oss << "Stuff";
oss.str() = "";  // Should have been oss.str( "" );

The third line is creating a temporary variable and assigning it the new ""
value, then it disappears.  Couldn't g++ have warned me of an unused temp? I
know I have seen it do things like that before.

Thanks
