DMD version: 2.063.2

The value of all variables in V should be zero, but the output shows they
aren't.

---------------
struct V {
    union {
        struct {
            float x = 1;
            float y = 1;
        float z = 1;
        }
        struct {
            float r;
            float g;
        float b;
        }
    }
}
import std.stdio;
void main() {
    writeln("V(", V.init.x, ", ", V.init.y, ", ", V.init.z, ", ", V.init.r, ",
", V.init.g, ", ", V.init.b, ")");
    writeln(V.init);
    writeln(V(V.init.x, V.init.y, V.init.z));
}
---------------

V(0, 0, 0, 0, 0, 0)
V(0, nan, nan, 0, nan, nan)
V(0, 0, 0, 0, 0, 0)

 struct V {
     union {
         struct {
             float x = 1;
             float y = 1;
         float z = 1;
         }
         struct {
             float r;
             float g;
         float b;
         }
     }
 }
I posted the wrong code, the correct one is: struct V { union { struct { float x = 0; float y = 0; float z = 0; } struct { float r; float g; float b; } } } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I wanted to add that this:

void main() {
  assert(V.init is V());
}

It would *appear* that the compiler is confused as to *what* the initial state
of V is.
