Considering the following code, both methods should print 1. I get 1245056 on
the second call. Bug was present in dmd 1.056, i upgraded to 1.062 and it
remains the same.

module main;

import std.stdio;
import std.stdarg;

void test_ok(int i, ...) {
    writefln(va_arg!(int)(_argptr));
}

void test_fail(out int x, ...) {
    writefln(va_arg!(int)(_argptr));
}

void main() {
    int i;
    test_ok(i, 1);
    test_fail(i, 1);
}
