Original Bugs that caused BC break.
php -r ' $arr = array(0=>0,-1=>0); $arr[] = 0; '
This caused a segmentation fault in 4.2.3

Here is one example of the problem.
php -r ' $arr[-2] = 1; $arr[] = 2; print_r($arr); '
PHP 4.2.3
Array
(
    [-2] => 1
    [-1] => 2
)

PHP 4.3.X/5.X (wo/patch)
Array
(
    [-2] => 1
    [0] => 2
)

PHP 4.3.X/5.X (w/patch)
Array
(
    [-2] => 1
    [-1] => 2
)
