Printf() in loops

[Twinny]

Using printf() in loops seems to break the loop.

PHP Code:

function onCreated()
{
  this.array ={"I","really","really","like","pie"};
  for (temp.t : this.array)
    printf("[Blah?]: %s",temp.t);
  echo("--");
  for (temp.t : this.array)
    echo(format("[Blah?]: %s",temp.t));  
} 


echos

PHP Code:

[Blah?]: I
--
[Blah?]: I
[Blah?]: really
[Blah?]: really
[Blah?]: like
[Blah?]: pie 


Any idea why printf is breaking the loop? This was tested on Zodiac.
