That's the normal behavior. See:
http://de.php.net/manual/en/language.basic-syntax.comments.php
"%>" is returning to HTML mode. But at this point the opened "{" from
the if is not closed, and it's not closed till the end of the file.
That's the error message.

Description:
------------
A parsing error occurs if a pattern looking like a closing ASP tag
appears inside a line comment (beginning by '//'), in a PHP engine
having 'asp_tags = On' in the 'php.ini' file.
If I remove the "//" comment, I have a big "Line 2" visible, and there
is no bug.
If I use a "/* */" style comment instead, there is no bug.
If I put quotes around "140%" in the "size" attribute, there is no bug.
If I set the "asp_tags" options to "Off", or if I remove it, there is no
bug.
Removing the 'if' condition around the comment results in another kind
of problem (no error, but part of HTML code visible).
I found this because I was trying to install the latest version of OCS
Inventory (http://www.ocsinventory-ng.org/), and I didn't understand why
I got a white page and a PHP parse error after the first step of
installation: I have 'asp_tags = On' in 'php.ini', and there is
effectively a commented out '%>' pattern in their code.
Looks like a little to Bug #4879 (more than 10 years old).
Test script:
---------------
<html>
<head><title>Asp tag bug</title></head>
<body>
Line 1<br>
<?php
if (true) {
//echo "<font size=140%>Line 2</font><br>";
}
?>
Line 3<br>
</body>
</html>
Expected result:
----------------
Two text lines in browsers's Window :
"Line 1"
"Line 3"
Actual result:
--------------
A white page, and the following error in Apache log :
PHP Parse error: syntax error, unexpected $end in
/var/www/[...]/asp_tag_bug.php on line 13
