Not a bug report but a feature request (the link sent me here...)

It'd be nice if session variables that are references stayed references throughout a session.  Ex:

page1.php:
session_start();
session_register("a"); session_register("b");
$a = 4;
$b = &$a;
print "a = $a, b = $b";

page2.php
$a = 7;
print "a = $a, b = $b";

-----
In page1 it works as expected, but in page2 $b is no longer a reference to $a, they both just have the same value at the beginning of the script.

It's be nice if $b stayed a reference to $a throughout the session.  Don't know how plausible that is though.
