1 // Bug 717104 - Unreachable debuggee globals should not keep their debuggers
2 // alive. The loop is to defeat conservative stack scanning; if the same stack
3 // locations are used each time through the loop, at least three of the
4 // debuggers should be collected.
5 //
6 // This is a slight modification of gc-09.js, which contains a cycle.
