Description:
------------
glibc detected - double free or corruption - on fclose for socket

code will work fine through the web interface, however, will not work from the command line

will get double free or corruption when issuing fclose or when php does the automatic fclose at the end.

It will only be an issue for very few blades, however, when it is an issue, it is reproducible 100% of the time.

When it does not work, one thought is it might be when the blade on the other end closes the connection ahead of time.


./configure --prefix=/usr/local/php --with-config-file-path=/etc/php.d --with-zlib --with-apxs2=/etc/httpd/bin/apxs --enable-magic-quotes --enable-sockets --with-openssl --enable-magic-quotes --with-mysql=/usr/local/mysql --enable-debug

Reproduce code:
---------------
#!/usr/src/php-5.2.0/sapi/cli/php

<?php

$ip = '';
$username = '';
$password = '';

$ilo_xml ='<RIBCL VERSION="2.0">
<LOGIN USER_LOGIN="' . $username . '" PASSWORD="' . $password . '">
<RIB_INFO MODE="read">
<GET_FW_VERSION/>
</RIB_INFO>
</LOGIN>
</RIBCL>';

$ssl_handle = @fsockopen ('ssl://' . $ip, 443, $error_number, $error_text, 10);
$split_ilo_xml = split ("\n", $ilo_xml);
stream_set_timeout ($ssl_handle, 10);
fwrite ($ssl_handle, '<?xml version="1.0"?>' . "\r\n");
$ssl_meta_data = stream_get_meta_data ($ssl_handle);
foreach ($split_ilo_xml as $value) {
	fwrite ($ssl_handle, $value . "\r\n");
}
do {
	$data = fgets ($ssl_handle, 1024);
	$data = trim ($data);
	$data = str_ireplace (array ('<', '>'), '', $data);
	print "\n" . $data . '<br />';
} while (! feof ($ssl_handle));
fclose ($ssl_handle);

?> 

Expected result:
----------------
This code is for logging into the back end ilo on a blade. When it works correctly, I will see xml report back.

Actual result:
