void main(string[] args)
{
    if(!args.length) return;

    foreach(i; 0 .. 1)
        main(null); // ok, C linkage used

    foreach(i; 0 .. 1)
        (&main)(null); // also ok

    foreach(i; 0 .. 1)
    {
        auto p = &main; // D linkage used
        p(null); // stack corruption, results in Access Violation
      //asm { add ESP, 0x8; } // uncomment to fix
    }
}

Note: do not mark `main` as `extern(C)` because it will lead to not calling
runtime initialization stuff.
