    [deoptimizer] Fix bug in OptimizedFrame::Summarize · 3353a7d0
    Georg Neis authored
    OptimizedFrame::Summarize is used by debugger features etc
    to inspect the frame of an optimized function (and the virtual frames
    of functions that got inlined). It could end up materializing a JSArray
    with the same backing store as one that would later get left-trimmed,
    resulting in a dangling elements pointer. This CL fixes that by creating
    a fresh copy of the elements store instead.
