ok, now I think that Field_blob cannot support unpacking into anything else but record[0]. It allocates the memory and only can track one pointer. Fine, but still it should not just silently update wrong record buffer. It could have an assert that to == record[0], and in non-debug mode simply return without updating anything if that condition is false.
