Currently I'm using: PHP Version 5.5.11 on windows. On most of my clients servers php version
is 5.2-5.5. Recently, one of the servers has been updated to version 5.6.9 and the difference is
just there.

See this example: http://phpbug.studiostron.eu/ its
output of the same script + phpversion()

According to http://3v4l.org/L8GsZ this behavior has stayed the
same for all PHP versions - apart from a short regression interval in PHP 7. Are you sure the code
you tested on older versions wasn't in some way different?

in previous versions of php script worked differently. The variable $d was assigned to different
array with unmodified IAP.
It seems to me that it is a a bug because if I wanted to return a reference to the array, which is
inside a function test() I would done it differently.
Sorry for my english, I hope that everybody understands what I mean.

Sorry, I'm not sure I see what the issue is here. In test() you're modifying the internal
array pointer (IAP) of $a and then returning $a (including the modified IAP). Then in the main
script you assign this to $d (still with modified IAP that is at the end of the array) and try to
iterate further with it - which fails. Isn't this how it is supposed to work?
