        <pre>Ah, I think it is coming from this in WriteBarrier.h:

template&lt;class T&gt; inline void validateCell(T cell)
{
    ASSERT_GC_OBJECT_INHERITS(cell, std::remove_pointer&lt;T&gt;::type::info());
}

by way of WriteBarrierInlines.h:

inline void WriteBarrierBase&lt;T&gt;::set(VM&amp; vm, const JSCell* owner, T* value)
{
    ASSERT(value);
    ASSERT(!Options::useConcurrentJIT() || !isCompilationThread());
    validateCell(value);
    setEarlyValue(vm, owner, value);
}

Testing a fix.</pre>
