/* This looks to be a bug in the DXIL validation logic. When replicating these I/O dependency
/* This was a bug in the DXIL validation logic prior to 1.8. When replicating these I/O dependency
* tables from the metadata to the container, the pointer is advanced for each stream,
* and then copied for all streams... meaning that the first streams have zero data, since the
* pointer is advanced and then never written to. The last stream (that has data) then has the
* data from all streams written to it. However, if any stream before the last one has a larger
* size, this will cause corruption, since it's writing to the smaller space that was allocated
* for the last stream. We assume that never happens, and just zero all earlier streams. */
