The current implementation of for-of in porffor duplicates code. Nested for-of loops (which appear in the benchmark) make this much worse and causes more instructions to generate than it can handle. The crash here in particular is because porffor uses array.push(...values); to push values into an array, which breaks with too many parameters.
