[Question][Hw5] pp error

[kws1207]

While debugging, I put the following:

let _ = Memory.pp Format.std_formatter fc in

But the following error occurs:

Cannot find lhs of i32 %div4
Fatal error: exception Not_found

I don't know any other debugging tool rather than pp. In such case, how can I debug?

I recommend you to find which timing and which variable invoke an exceptions.
