AttributeError exception raised on Linux Fedora 20 (LLDB 3.4.2)

[lacombar]

Hi,

I was experimenting today with lldb-v8 and a core produced by node 0.10.36. The following exception was raised when attempting to run `jsstack':

(lldb) jsstack
unknown type: False
Traceback (most recent call last):
  File "/data/src/misc/lldb-v8/v8.py", line 781, in jsstack

    raise AttributeError
AttributeError

Here is the stack viewed from lldb:

generated by the following very trivial script:

var foo = function () { console.trace(); process.abort(); }
var bar = function () { foo(); }
var baz = function () { bar(); }
baz();

it fails because the object computed is not a heapobject
