Bisect done.
This is the revision that fixed it on trunk:
r199076 <<a href="http://trac.webkit.org/r199076">http://trac.webkit.org/r199076</a>> -- JSC should use a shadow stack version of CHICKEN so that debuggers have the option of retrieving tail-deleted frames <a class="bz_bug_link

Is quite a large changeset, not sure if we could backport this to the 2.12.x branch</pre>
