strange behaviour of GSPrintf

Hi,

I observed that when I compile the piece of code at the end
gmake debug=yes

then I get the following output:

$ obj/ArrayTest
2006-09-17 21:34:54.322 ArrayTest[31262] Msg3
2006-09-17 21:34:54.323 ArrayTest[31262] Msg4
Msg2$

when I change the line 
  GSPrintf(stdout, @"%@", [outArray objectAtIndex: 1]);
to 
  GSPrintf(stdout, @"%@\n", [outArray objectAtIndex: 1]);

I get the following output:

$ obj/ArrayTest
Msg2
2006-09-17 21:36:38.694 ArrayTest[28187] Msg3
2006-09-17 21:36:38.695 ArrayTest[28187] Msg4
$                                                

is that explainable somehow? I compiled the sources from svn with gcc 3.3.5 
and ffcall 1.9 on an actual OpenBSD snapshot.

kind regards
Sebastian

  NSLog(@"%@", [outArray objectAtIndex: 2]);
