    Description

      There is an incorrect assert in lod_ea_store_resize which leads to an LBUG with very high stripe counts.  (I didn't calculate precisely, but 1300 is OK and 1600 triggers the bug.)

      The fix is trivial.  Patch forthcoming.

            [Edit]

            This was due to a bug in SEL, now fixed.  Whoops.
