// Bug 717104 - Unreachable debuggee globals should not keep their debuggers

// alive. The loop is to defeat conservative stack scanning; if the same stack

// locations are used each time through the loop, at least three of the

// debuggers should be collected.

//

// This is a slight modification of gc-09.js, which contains a cycle.
