import std.stdio;

struct Base(bool T)
{
    static if (T)
    {
        int x;
    }

    int y;
}

void main()
{
    alias Base!false Type;
    auto fields = [__traits(allMembers, Type)];

    writeln(fields);  // writes ["x", "y"]
}

"x" does not exist in the Base!false instance.

Actually it's broken for non-template types too:

import std.stdio;
import std.traits;

struct Base
{
    version(none)
    {
        int x;
    }

    int y;
}

void main()
{
    auto vals = [__traits(allMembers, Base)];
    writeln(vals);  // writes ["x", "y"]
}
