[Swift-devel] Fold tests fail.

[Yadu Nand]

Hi,

I am trying to do fold of results in swift, and I see some very weird
results/errors.

Here's my code :
https://github.com/yadudoc/swift-basics/blob/master/stress/patterns/x_treefold.swift
I've also attached it, in case that's easier.

On 0.93, Here's a clip of the output showing that integer equality is
failing
Start, Mid : (0, 1)  Mid+1, End : (2, 2)
Equal start != mid  0 : 1
Equal mid+1 == end
Equal start != mid  3 : 3        <--- This should'nt happen ?
Equal start != mid  4 : 4        <--- This should'nt happen ?
Start, Mid : (3, 3)  Mid+1, End : (4, 4)
Equal start != mid  3 : 3         <--- This should'nt happen ?

On 0.94, I get an runtime error :
Execution failed:
 Equal start != mid  0 : 2
Equal start != mid  3 : 4
Internal type error. Expected a Integer. Got null

On Swift-faster, The code does not get past compilation as a circular
dependency
is detected. Do we not support recursion on swift-faster branch ?

 at org.griphyn.vdl.karajan.Loader.main(Loader.java:165)
Could not start execution:
org.griphyn.vdl.karajan.CompilationException: Circular procedure dependency

I would really appreciate help in understanding what is going on here.
