Description Saam Barati 2016-04-07 13:28:59 PDT
The Type Profiler might profile JS code that uses DebuggerScope and accesses properties
on it. Therefore, it may have a DebuggerScope object in its log. Objects in the log
are subject to having their getOwnPropertySlot method called. Therefore, the DebuggerScope
might not always be in a valid state when this happens. The assertion is therefore invalid.
