[Swift-devel] simple parameter test hangs

[Michael Wilde]

-- the following program hangs (using 0.3):

type messagefile;

type params {
   int x;
   int y;
}

(messagefile t) pecho (params p[] ) {
     app {
         echo p[0].x p[0].y stdout=@filename(t);
     }
}

messagefile outfile <"hello2.txt">;

params z[];
z[0].x = 111;
z[0].y = 222;

outfile = pecho(z);

-- while this one works:

type messagefile;

type params {
   int x;
   int y;
}

(messagefile t) pecho (params p) {
     app {
         echo p.x p.y stdout=@filename(t);
     }
}

messagefile outfile <"hello2.txt">;

params z;
z.x = 111;
z.y = 222;

outfile = pecho(z);

-- swift says:

$ swift t2.swift
Swift v0.3 r1319 (modified locally)

RunID: 20071004-2312-mlnzad63

(and then it hangs)

-- heres the log:

java doesnt seem to be burning cpu - looks more like a hang than a loop; 
doesnt seem to be waiting on stdin either, as far as i can tell.
