[Swift-devel] unitialized error when swift app returning a non-file type

[Ketan Maheshwari]

Consider the following variant of above example:

type file;

app (file _b) s_app(string a){
 str_app a @_b;
}

file b[]<simple_mapper; location=".", prefix="b_",suffix=".out">;

foreach i in [0:10]{
   b[i]= s_app("hello");
}

And the corresponding bash script that app links to:

#!/bin/bash

echo "$1">$2

This variant exhibits the same pattern as the previous one except that b
now is a file type variable. The original example which did not work
involved b as a non-file type variable (string).

Since this one works, I understood the one with other types should also
work.
