The following wasm program should produce a memory out of bounds exception when `fill_oob` is called: ``` (module (import "env" "memory" (memory $mem0 1 1)) (func (export "fill_oob") (memory.fill (i32.const 0) (i32.const 42) (i32.const 65537)) ) ) ``` Right now, JSC will throw "Out of bounds table access" instead.
