Bug description: Strange math when squaring
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:
