IIRC I have even cooked a patch for it, but didn't apply for a reason.

Description:
------------
I know that the code below is senseless in this form, but I came across
it accidentally.
This code prodcues a dump of $b object variable which contains two
members - 'd' and a strange member shown as ':private'. The name is
':private' when the last line is not present. When this line (echo
$a->{4} or similar) is put in the script, var_dump ($b) starts to
produce a different dump on each script run. A sample output is shown
below.
Reproduce code:
---------------
<?
$a['d'] = 4;
$a[''] = 5;
$b =(object)$a;
var_dump($b);
echo $a->{4};
Expected result:
----------------
Maybe
object(stdClass)#1 (2) { array (['d'] => int(4), [''] => int(5)) }
Actual result:
--------------
A sample result is
object(stdClass)#1 (2) { ["d"]=> int(4) ["¤:private"]=> int(5) }
But '¤' is often another symbol or a sequence of symbols. Also it is
sometimes just [":private"].
