How to solve disasm: stack underflow when call exec.NewVM(module)

[lowesyang]

i try to exec the wast file and get disasm: stack underflow.

After i open debugMode and add extra logger print, and find out the error occurs in ops.End or ops.Else case:

curDepth is -1. prevDepth is 2. elemsDiscard is -3

Seems like set_local op push -1 to the top of stack. And then next op is op.end, makes the curDepth = -1, and elemsDiscard becomes -3, which throw ErrStackUnderflow.

What are the possible problems for this error? How can i solve it?

Opened an issue in assemblyscript and seems like this is the unexpected result of wagon.

(The error above is from the same wast code)

apologies for the belated answer (holidays).
@vibhavp would be the one with the most expertise on this.

(feel free to reopen if that's still an issue for you)
