Maciej Szymkiewicz commented on SPARK-30629:
--------------------------------------------

Although I still have some doubts... This should terminate (at least for some 
values of {{x}})

{code:r}
  f <- function(x) {
    if(x > 0) {
      f(x - 1)
    } else {
      x
    }
  }
{code}

but it still fails with the same exception (build from 
d5b92b24c41b047c64a4d89cc4061ebf534f0995)

{code}
> SparkR:::cleanClosure(f)
Error: node stack overflow
{code}

> This problem surfaced while handling SPARK-22817. In theory there are tests, 
> which cover that problem, but it seems like they have been dead for some 
> reason.
> Reproducible example
> {code:r}
> f <- function(x) {
>   f(x)

> SparkR:::cleanClosure(f)
> {code}
