New Comment:
This slightly modified script shows the bug without massive output:
<?php
ini_set('memory_limit', 100);
ob_start();
$i = 0;
while($i++ < 5000) {
echo str_repeat("lol", 42);
}
ob_end_clean();
?>

Description:
------------
When memory_limit is reached, and one is using the output buffering
functions, instead of just dying with an "out of memory" error, the
contents of the buffer are spilled onto stdout.
The output_buffering ini setting wasn't set to any particular limit.
Reproduce code:
---------------
<?php
ob_start();
$i = 0;
while($i++ < 10000000) {
echo str_repeat("lol", 42);
}
ob_end_clean();
/*Note that the 10,000,000 number varies according to your
memory_limit*/
Expected result:
----------------
STDERR: Fatal error: Allowed memory size of 134217728 bytes exhausted
at /home/flebron/cvs/php/php5.3-200806291230/main/output.c:395 (tried to
allocate 133693441 bytes) in /home/flebron/cvs/php/ob.php on line 5
STDOUT: Nothing
Actual result:
--------------
STDERR: Fatal error: Allowed memory size of 134217728 bytes exhausted
at /home/flebron/cvs/php/php5.3-200806291230/main/output.c:395 (tried to
allocate 133693441 bytes) in /home/flebron/cvs/php/ob.php on line 5
STDOUT: The text in the buffer is printed to stdout (millions of
"lolol"s).
