Description:
------------
let $b=array(# , #).
then

list($a,$b) = $b

fails.

moar precise: after the assigment we'd get

$b = $b[1],
$a = {
  $b[1][0], if $b[1] is a string/array
  NULL, if $b[1] is a number
}

if $b[1] is an object we'd get a fatal error 'cant convert object->array'.


//////////////////

it works correctly if we try list($b,$a)=$b. so an easy fix could be forged in just 2 additional steps: swap arguments * do the usual work * swap results

Test script:
---------------
$a = 1;
$b = array('ohno','yeah');
list($a,$b) = $b;
print_r(array('a'=>$a,'b'=>$b));

Expected result:
----------------
Array
(
    [a] => ohno
    [b] => yeah
)


Actual result:
--------------
Array
(
    [a] => y
    [b] => yeah
)
