Crash with foreach handle Variadic Templates

[lili]

Hi:
    I'm writing an OS kernel run in i386 mode.
    where is crash when I implement a std.stdio.write like 
function and pass a long type argument. see code below:

  void printlnA...)(A a)
  {
     foreach(v;a)
     {
     }
  }

  long xr=100;
  println(xr); //crash
  println(100); //ok

  compile with ldc2 -betterC -m32
  then run
  qemu-system-i386 -kernel kernel -serial stdio -m 1024M

  Is where has a bug in implementation.
