Anything unusual about your configuration? i.e., php.ini changes or Zend extensions? I cannot reproduce this.

Thought it was a general bug, but it's not...

If you replace 
"$myVar = MyClass::$classVar;"
with
"$myVar = ErrorFetcher::$classVar;"
you will se the error...

Is this a bug, or is it me how have chosen a bad name for my class....?

This is the strangest thing...

Today my PHP application works fine, but I am sure that it didn't work yesterday. No changes in the code, only a reboot of my computer since yesterday....

YES. I managed to reproduce the error in my PHP application!
(One line was changed...)

I will now try to make a test application I can post here which generates the same error... Stay tuned...

I have created an application which reproduces the error. And now I see that the error is caused by something other than I thought in the beginning...

Put the following files in the following folder structure, and load 'test.php'...

/test.php
/class_files/ErrorHandler.php
/class_files/TestClass.php
/other/Other.php

#test.php#
<?php
function __autoload($className) {	
	require_once("class_files/" . $className . ".php");
}

//Uncoment this line to bypas the bug...
//require_once("class_files/TestClass.php");

class Test
{	
	public function Test()
	{		
		$errorHandler = new ErrorHandler();
		
		require_once("Other/Other.php");		
		$other = new Other();			
	}	
}

$test = new Test();
?>

#TestClass.php#
<?php
class TestClass
{
	public static $staticVar;
	
	public function TestClass()
	{
		//Set ErrorHandler
		set_error_handler(array($this, 'handlePhpError'));		
	}
}
?>

#ErrorHandler.php#
<?php
class ErrorHandler
{
	public function ErrorHandler()
	{
		error_reporting(E_ALL);
		set_error_handler(array($this, 'handlePhpError'));		
	}
	
	public function handlePhpError($type, $msg, $file, $line)	
	{
		$myVar = TestClass::$staticVar;	
		echo "Error!";			
	}
}
?>

#Other.php#
<?php
class Other 
{
	//Produces warning!
	var $temp = 'temp';
	
	public function Other()	{}	
}
?>

Sorry.

Replaced all my PHP files with the files in
http://snaps.php.net/win32/php5-win32-latest.zip.

Still same error...

(I'am using the built-in IIS in Windows XP SP2)

 Output from 'test.php':
