Yes, I think you've nailed it (a nice debugging effort!).  We strip
sections early based on their sizes before relaxation.  Your .sdata2
section is empty except for the padding, and the layout before
relaxation just happens to need no padding.  After relaxation you need
padding but the section with the padding has gone.  :-(
