        <pre>I strongly suspect these globals were discarded by /OPT:REF. When this happens,
those fields will remain unrelocated, and they typically contain zeroes.

Fixing it should be easy, I think we can just discard such symbol records from
the globals stream if the segment index/offset pair is zero. IIRC valid
segments start at 1 (maybe?), so zero should be invalid.
