Getting errors on memory.grow and memory.size

[theblockstalk]

I create a new Wat project in

I edit a wat file with memory.grow and memory.size, such as the one below (just for illustration):

(module
  (func $add (param $lhs i32) (param $rhs i32) (result i32)
    get_local $lhs
    get_local $rhs
    memory.grow
    memory.size
    i32.add)
  (export "add" (func $add))
)

and on build this gets the following errors

    memory.grow
test.wat:6:5: error: unexpected token memory.size.
    memory.size

These are the same errors reported in WebAssembly/wabt#852

Perhaps you need to update to the latest version of wabt in Studio?
