[Swift-devel] array_mapper hangs

[wilde at mcs.anl.gov]

I think the script is hanging because its trying to return physD[] without ever setting the return array parameter physD (or any member of it):

app (file physD[]) maptest(){
> touch @filename(physD[0]) @filename(physD[1]);
> }

The following examples don't use @filename in maptest. am3.swift hangs, am4.swift works. The difference is that am4 puts a value in f[] and am3 does not.

::::::::::::::
am3.swift
::::::::::::::
type file;

app (file physD[]) maptest() {
   echo "hi";
}

file f[];

f = maptest();
::::::::::::::
am4.swift
::::::::::::::
type file;

app (file o) echo (string s) { echo s stdout=@o; }

(file physD[]) maptest() {
   physD[0] = echo("hi");
}

file f[];

f = maptest();
