Subject: Regarding serialize
From: chrisstocktonaz@gmail.com (Chris Stockton)

Hello,

I have came across some strange behavior today, after some time I got
it to the simplest form to reproduce. I have not yet attempted to
patch/investigate the code within php source, I want to first confirm
this is indeed a problem and I haven't just had a long day, as well as
verify it is not a known issue. I have searched the bug tracker; found
nothing similar.

Below is reproducible code, tested on php 5.3.0 release build, as well
as the latest snapshot and a random version installed in a yum
repository (5.1.6).

Regards,

-Chris

$base = new testSerialize;

$str1 = 'O:13:"testSerialize":1:{s:7:"*_foo";a:0:{}}';
$str2 = serialize($base);

var_dump($str1);
var_dump($str2);
var_dump($str1 == $str2);

var_dump(escapeshellarg($str1));
var_dump(escapeshellarg($str2));
