What seems to have happened here is the field was changed to become a
pointer in 77947c51c.  It's not incorrect to use MemSet() to zero out
the pointer field.  What it does probably do is confuse the casual
reader into thinking the field is a struct rather than a pointer to
one.   It's probably worth making that consistent with the other
fields so nobody gets confused.

Can you add a CF entry for PG16 for this so we come back to it after we branch?
