/*
 * Test "Jumping backward to the end of a DisplayObject's lifetime (with events: onConstruct, onUnload)"
 *
 * Timeline:
 * 
 *   Frame  | 1 | 2 | 3 | 4 | 5 | 6 |
 *  --------+---+---+---+---+---+---+
 *   Event  |   | P | R | * | J |   |
 * 
 *  P = place (by PlaceObject2)
 *  R = remove (by RemoveObject* tag)
 *  J = jump
 *  * = jump target
 *
 * Description:
 *
 *  frame2: a static DisplayObjects is placed at depth 3 (-16381) [ a red square ]
 *          Both onConstruct and onUnload event handlers defined.
 *  frame3: DisplayObject at depth 3 (-16381) removed
 *  frame5: jump back to frame 4 and stop
 *
 * Expected behaviour:
 *
 *   After jump back, the onConstruct event handler for the red square has been invoked twice.
 *
 * run as ./loop_test7
