Found by the test case in
https://code.google.com/p/chromium/issues/detail?id=179522

<script>
var Context0= new webkitAudioContext()
var Analyser0=Context0.createAnalyser();
var WaveShaper0=Context0.createWaveShaper();
var Convolver3=Context0.createConvolver();
Analyser0.connect(WaveShaper0);

WaveShaper0.connect(Context0.destination);
Convolver3.connect(Analyser0);

setInterval(function(){
Analyser0.disconnect();
},4)
setTimeout(function(){location.reload()},1000)
</script>
