Describe the bug
The wat file:
(module
(type $0 (func))
(func (export "start") (type $0))
(memory (;0;) 65536)
)
The go file:
package main
import (
"fmt"
"github.com/wasmerio/wasmer-go/wasmer"
"io/ioutil"
)
func main() {
wasmBytes, _ := ioutil.ReadFile("./tmp.wasm")
engine := wasmer.NewEngine()
store := wasmer.NewStore(engine)
// Compiles the module
module, err := wasmer.NewModule(store, wasmBytes)
if err != nil {
fmt.Println("Failed to compile module:", err)
}
importObject := wasmer.NewImportObject()
instance, err := wasmer.NewInstance(module, importObject)
if err != nil {
panic(fmt.Sprintln("Failed to instantiate the module:", err))
}
func1, err := instance.Exports.GetFunction("start")
if err != nil {
panic(fmt.Sprintln("Failed to get the `start` function:", err))
}
result, err := func1()
fmt.Println(result)
}
Steps to reproduce
wat2wasm tmp.wat
go run tmp.go
Expected behavior
Successfully allocate memory in the wat file.
Actual behavior
wasmer-go prints:

However, if execute the command 'wasmer run tmp.wasm -i start', wasmer could successfully allocate the memory.
