if changing the declaration in a.inc.php fixes it then you must
NOT be including b.inc.php form the global scope. which means $a will not
be in the global scope unless you tell php to put it there, instead $a
is probably part of a function scope.
e.g. you have a function like so:
function getNewBee()
{
require_once('b.inc.php');
$b =& new b;
return $b;
}
in the above $a lives in the scope of the function call to
getNewBee() and NOT in the global scope.

doing it like this means you don't need to specify
$a as 'global' - its already in the scope of the current function
(method), specifying it as 'global' will make it available everywhere
though.
