Status: NEW

(Core :: JavaScript Engine, defect)

Build ID: 20140623175014

Steps to reproduce:

In lldb, set a breakpoint at IsEvalCacheCandidate. Then, in the js shell:
    
    var a = [];
    for (var i = 0; i < 2; i++)
        a[i] = eval("print('hello world')");


Actual results:

The breakpoint was never hit. In ~EvalScriptGuard, if (lookup_.str) failed, and IsEvalCacheCandidate was never called.


Expected results:

IsEvalCacheCandidate should be called, and the eval should be cached.
