Description:
------------
I was running a benchmark script to test out certain things on my
localhost.  Once of my scripts involved performing randomly large math
calculations within comments, increasing expotentially.

Reproduce code:
---------------
<?php

$st = array_sum (explode (' ', microtime ()));

ob_start ();

for ($i = 1; $i < 10000; $i++) {
    echo "<!-- Hello, World! " .  ($i % round(sqrt($i*2))) ^ $i .  "
-->\n";
}

ob_end_flush ();

echo round ((array_sum (explode (' ',microtime ())) - $st), 5) . "\n";

?>

Expected result:
----------------
I expected for the page to hesistate for a minute or so, and then print
out the expected benchmark along with the comments and numbers within
them.

Actual result:
--------------
Strange HTML/Chinese characters:

(e.g.,
•&#5389;&#3352;”l•&#5389;&#3355;”l•&#5389;&#3354;”l•&#5389;&#3349;”l•&#5389;&#3348;”l•&#5133;&#3357;”l•&#5133;&#3356;”l•&#5133;&#3359;”l•&#5133;&#3358;”l•&#5133;&#3353;”l•&#5133;&#3352;”l•&#5133;&#3355;”l•&#5133;&#3354;”l•&#5133;&#3349;”l•&#5133;&#3348;”l•&#5901;&#3357;”l•&#5901;&#3356;”l•&#5901;&#3359;”l•&#5901;&#3358;”l•&#5901;&#3353;”l•&#5901;&#3352;”l•&#5901;&#3355;”l•&#5901;&#3354;”l•&#5901;&#3349;”l•&#5901;&#3348;”l•&#5645;&#3357;”l•&#5645;&#3356;”l•&#5645;&#3359;”l•&#5645;&#3358;”l•&#5645;&#3353;”l•&#5645;&#3352;”l•&#5645;&#3355;”l•&#5645;&#3354;”l•&#5645;&#3349;”l•&#5645;&#3348;”l•&#6413;&#3357;”l•&#6413;&#3356;”l•&#6413;&#3359;”l•&#6413;&#3358;”l•&#6413;&#3353;”l•&#6413;&#3352;”l•&#6413;&#3355;”l•&#6413;&#3354;”l•&#6413;&#3349;”l•&#6413;&#3348;”l•&#6157;&#3357;...)
