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. |
|

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