    The bug here is that we add empty JSValues to the sparse map, and then set them
    - but a GC may occur before doing so (due to a call to reportExtraMemory cost).
    We may want to consider making it safe to mark empty JSValues, but the simple &
    contained fix to this specific bug is to just initialize these values to
    something other than JSValue().
    
    * runtime/JSArray.cpp:
    (JSC::SparseArrayValueMap::add):
        - Initialize sparse map entries.
