518314 - native class finalize function not called in some cases

Status: RESOLVED INVALID

(Core :: JavaScript Engine, defect)

Description

[Franck]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3
Build Identifier: trunk (tracemonkey-de30e660f263)

None of my native finalize function (JSFinalizeOp) get called after I run the following JavaScript code:

  var b = new Array();
  for ( var i = 0; i < 2; i++ )
    b.pop;
  Print('Done.\n');

If the loop runs only one time (for 0 to 1), the problem does not appear any more.


Reproducible: Always

The custom global object is leaking for some reason todo with the JIT.

note: if the script is run using JS_EvaluateScript instead of JS_CompileScript + JS_ExecuteScript, everything works fine.

Hey Franck,
Can you still reproduce this or should we close it?
