            Bug ID: 169237
           Summary: The SamplingProfiler should do a sanity check on the
                    callFrame pointer when walking the stack.
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mark.lam at apple.com

This is needed if the profiler gets the callFrame pointer from vm.topCallFrame.  If topCallFrame is stale, it may point to un-initialized memory, and the previousCallFrame pointers it gets from there may be invalid.
