	Minimal repro for a suspected V8 optimizer bug in Chrome 150.

	Pattern: a hot method fills a Float32Array; when full, it passes the array to
	a callback that transfers its ArrayBuffer via MessagePort.postMessage
	(detaching it), then immediately replaces it:

	this.buffer = new Float32Array(bufferLength);

	PRINT "**********************************"
	REPEAT
	PRINT "Key ";
	INPUT A$
	PRINT "SORRY WRONG KEY!!!"
