;; NOTE: Assertions have been generated by update_lit_checks.py and should not be edited.
;; RUN: wasm-opt %s --safe-heap -S -o - | filecheck %s

;; Test that safe-heap does not crash when the start function calls an imported
;; function. The findCalledFunctions helper transitively walks all called
;; functions from the start, and must skip imported functions which have no body.
