[Swift-devel] iterate fails

Hi Mihael,

Is this the same issue that was discussed in this mail ->
http://lists.ci.uchicago.edu/pipermail/swift-devel/2013-March/010109.html

I am seeing this script failing on trunk (but not on 0.94). The internals
stress test
runs this script which does an assignment to an array within an iterate
loop ->
https://github.com/yadudoc/swift-basics/blob/master/stress/x_iterate.swift
The test-suite has some pending issues on trunk, which I haven't cleaned up
yet,
and which is why this went under the radar.

Here's the error I get when running stress/x_iterate.swift:
[yadunand at midway001 x_iterate-142712]$ swift x_iterate.swift -loops=5
Swift trunk swift-r7071 (swift modified locally) cog-r3787 (cog modified

Here's the error I'm getting when running Ketan's code :
Execution failed:
org.griphyn.vdl.mapping.InvalidPathException: Array index '[2]' not found
for out of size 2
swift:getFieldSubscript @ iterate, line: 93
Caused by: org.griphyn.vdl.mapping.InvalidPathException: Array index '[2]'
not found for out of size 2

Are these coming from the same bug ?

Thanks,
-Yadu
