gc-09.2.js (587B)


      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.
