Why does this code cause an exception and how should it be done right?

[code]void MainComponent::loadWave()  
{  
File file(T(“c:\wav.wav”));  
if (file.exists())  
{  
InputStream \*stream=file.createInputStream();  
if (stream)  
{  
WavAudioFormat format;  
AudioFormatReader \*reader=format.createReaderFor(stream, true);  
if (reader)  
{  
wave=new AudioSampleBuffer(2,(int)reader-\>lengthInSamples);  
wave-\>readFromAudioReader(reader, 0, (int)reader-\>lengthInSamples ,0, true, true);  
waveformComponent-\>setWave(wave);

```
			deleteAndZero(reader);
		}
		
		deleteAndZero(stream);	// <--- EXCEPTION!!
	}
}

```

}[/code]

The reader automatically deletes the stream that you give it, so just remove the line that deletes the stream and it’ll be fine.
