Try the following snippet:

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.PaintEvent;
import org.eclipse.swt.events.PaintListener;
import org.eclipse.swt.graphics.Font;
import org.eclipse.swt.graphics.Point;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class TestSnippet {
	
private static String text = "Label\r\n"; //$NON-NLS-1$

public static void main(String [] args) {
	final Display display = new Display();
	final Shell shell = new Shell(display);
	final Font font = new Font(display, "Tahoma", 16, SWT.BOLD);  //$NON-NLS-1$
	shell.addPaintListener(new PaintListener() {
		public void paintControl(PaintEvent event) {
			event.gc.setAntialias(SWT.ON);
			event.gc.setFont(font);
			event.gc.drawText(text, 10, 10);
			Point pt = event.gc.textExtent(text);
			event.gc.setClipping(10, 10 + pt.y, pt.x - 1, pt.y);
			event.gc.drawText(text, 10, 10 + pt.y);
		}
	});
	shell.setBounds(10, 10, 200, 200);
	shell.open ();
	while (!shell.isDisposed()) {
		if (!display.readAndDispatch()) display.sleep();
	}
	font.dispose();
	display.dispose();
}
}

Launch it as "Java Application" and get ArrayIndexOutOfBoundsException
If you remove '\r' from the text, no exception
If you don't set anti-alias (i.e. advanced flag - GDI+ support) it will also work.

Think it's a typo, hence priority == critical just to make sure this gets fixed asap.
