;; Checks that the start/stop exports are removed and that the data they

;; Two of the segments used here are active, so their offsets are trivial
;; to dirive. One segment is passive and its offset is derived from the
;; memory.init instruction.
;; Explictly use a data address that is larger then INT_MAX to verify
;; that these offset are correctly interpreted as unsigned.
