Summary

0001247: const and static field access is not possible from declaration of static fields

Description

When trying to access static fields during initialization of the class quercus ends up trying to load the class again and again (?)
Or if you try to access self::some_static_or_const_field during the same time you get an error stating that there is no such class "self"

tried this in:
resin-3_0-snap.tar.gz (2006/07/05)

Please look below for examples...

<?php
//File: crash.php

abstract class MyClass {

        const ONE = 1;
        const TWO = 2;
        const THREE = 6;

        protected static $affixMap = array(
                MyClass::ONE => 'Number 1',
                MyClass::TWO => 'Number 2',
                MyClass::THREE => 'Number 3'
        );
}

abstract class MyClass2 {

        public static $ONE = 1;
        public static $TWO = 2;
        public static $THREE = 6;

        protected static $affixMap = array(
                MyClass2::ONE => 'Number 1',
                MyClass2::TWO => 'Number 2',
                MyClass2::THREE => 'Number 3'
        );
}

abstract class MyClass3 {

        const ONE = 1;
        const TWO = 2;
        const THREE = 6;

        protected static $affixMap = array(
                self::ONE => 'Number 1',
                self::TWO => 'Number 2',
                self::THREE => 'Number 3'
        );
}
