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'
        );
}
