Sorry. I'm found it. It is not a bug.
The output of script was buffered by ob_start(); So header() does not
send warning. After I turned off buffering, I find a line out of php
section in config file of this soft.
With commented fpassthru() it outputs "\n\n".

Comment out the fpassthru() call and look at the page output.

No.
Right before @fpassthru ($f); headers sends. So, it can not be a new
line before fpassthru, otherwise header(""); write error message. But
there is no error messages in error_log, in browset output. And headers
are right.

You've probably got a newline at the top of your script, before the
<?php, or a trailing newline from some include or auto-prepend file.

Description:
------------
It seems, that fpassthru() is not binary safe
Reproduce code:
---------------
First 8 bytes of file (PNG image) on disk:
"89 50 4E 47 0D 0A 1A 0A"
<?php
//...
$f = @fopen( $filepath, "rb" );
@fpassthru ($f);
//...die();
?>
Expected result:
----------------
First 8 bytes of saved file via browser:
"89 50 4E 47 0D 0A 1A 0A"
Actual result:
--------------
First 8 bytes of saved file via browser:
"0A 89 50 4E 47 0A 1A 0A"
PS. Other bytes of files are equal.
