-----------------------------------
import std.stdio;
struct S { int a; }

int foo()
{
    S s;
    return bar(s.a);  // A
    //bar(s.a); return s.a; // B
}

int bar(ref int b)
{
    b = 5;
    return b;
}

enum y = foo();

void main()
{
    writeln(y);
}
-----------------------------------

Expected output: 5
Actual output: 0

Same thing occurs with either the "// A" line or the "// B" line uncommented. 
Also occurs with "out" instead of "ref".
