That's weird, but solves the problem.
So remains the suggestion to not require this specific order to work. It would be
helpful so we could simplify a "compiler" for each module of a system we have.

PHP expects the parent classes/interfaces to have been defined before the class that
extends/implements them.
If I change the order of the lines from code sample #2 (eIUJWp56) to read:
<?php
namespace Test {
class Second {
public function getMessage() {
return 'Message from Second Class';
}
}
interface TestInterface {}
abstract class Zero implements TestInterface {
public function __construct() {
// Using a second class
$second = new Second;
print $second -> getMessage();
}
}
class First extends Zero {}
}
?>
Then PHP 5.3.3, PHP 5.3.8 & PHP 5.4.0RC2 happily accept the file (no error).

Sorry, I don't know if it's allowed to do that, but is there any position about
this bug report?

Sorry about the code, it was my mistake.
The correct code for Code Sample #2 is: http://codepad.org/eIUJWp56
And as requested, the code of other file:
<?php
require_once 'Test.php';
try {
$first = new Test\First;
} catch( Exception $e ) {
echo $e -> getMessage();
}
?>
I tried without the try...catch() and with it and, in both cases the error remains.

It seems to me your 2 code samples are identical, just one has output attached.
Where's the interface?
Please provide a *complete* sample, i.e. if your including one file make clear what's in both
files, the one having a call to "require" and the one being required

Description:
------------
First at all, one consideration about one of the informations provided in this form is the PHP
version. I'm not using 5.3.6. I'm using 5.3.3, which is not listed. I f I chose
"earlier", the form won't submit.
I can be wrong, but I think this bug is not fixed in newer versions, because it's not a very
common use.
The whole thing is, when interfaces and classes are in the same namespace AND in same file, the
'implements' breaks the execution of the 'extends'. See Code #1
As expected I can see "Message from Second Class", without quotes.
But if I add a interface (see Code #2) I get a Fatal Error: "Class 'Test\Zero' not
found", when it could be expected the same result as before.
But why this is important, if the best practices are to develop by following an organized structure,
with each class/interface in its own file?
The thing is, when DEVELOPING, this kind of organization is very useful, but if the code produced
during development stage is a little library, if all the classes and interfaces are coded in one
single file, only one call to require_once is needed, and the code execution is three times faster
than when using an autoloader resource.
Note about CodePad's codes: I'd only saved the lines of code in this site, they don't
work from it, due PHP versions. But all the tests I made was in machine with the configurations
posted.
Test script:
---------------
[ Code #1 ]
http://codepad.org/pDOAiqBa
[ Code #2 ]
http://codepad.org/a42WgIT3
Expected result:
----------------
As said in Bug's Description, "Message from Second Class", witout quotes.
Actual result:
--------------
With the first code, I can see the expected result.
With the second code, as I said, I see a Fatal Error. If the stack traces helps, here is it:
Fatal error: Class 'Test\Test\Zero' not found in C:\root\Test\Library.php on line 5
Call Stack
# Time Memory Function Location
1 0.0004 326896 {main}( ) ..\index.php:0
2 0.0018 334024 require_once( 'C:\root\Test\Framework.php' ) ..\index.php:3
Dump $_GET
Dump $_POST
