Bug description:serializing an object that implements serializable
Description:
------------
Hello,
Create a class and implement Serializable, then use the serialize function
to return the value of serialize($this), apache crashes with an internal
server error, the apache error log reports a Premature end of script
headers error.
If line 17 is commented then the apache server does not crash.
Test script:
---------------
<?php
/**Simple class that is serializable and implements the serializable
interface */
class ImplementsSerializable implements Serializable {
/** returns the serialization of itself */
public function serialize() {
return serialize($this);
}
/** returns unserialized object passed in $serialized */
public function unserialize($serialized) {
return unserialize($serialized);
}
}
/** Create a new ImplementSerializable object */
$serializable = new ImplementsSerializable();
/** Store the serialized value in $serialized, this causes apache to crash,
with a
* Premature end of script headers error in the apache error log */
$serialized = $serializable->serialize();
/**point of execution does not reach here */
$unserialized = $serializable->unserialize($serialized);
echo "finished!";
?>
Expected result:
----------------
return value equal to the object serialized using the serialize function.
Actual result:
--------------
Apache crashes with internal server error and a Premature end of script
headers error.
