[Swift-devel] simple parameter test hangs

[Michael Wilde]

-- This program hangs in the same way:
type messagefile;

type file;

type params {
   string x;
   string y;
   file f;
};

(messagefile t) echo ( file p1, file p2, string s1, string s2 ) {
     app {
         echo @p1 @p2 s1 s2 stdout=@filename(t);
     }
}

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

string fn[] = ["f001","f002"];
file   fv[] <array_mapper;files=fn>;

params p;
p.x = "x1111";
p.y = "y2222";
p.f = fv[0];

messagefile outfile <"hello2.txt">;

outfile = pecho(p);

-- 
problem in passing a struct? I'll try to narrow it down.
