The script:

<?php

session_name("XSession");

function start() {
global $count;
session_start();
session_register("count");
var_dump($count);
}


function see() {
global $count;
print "Here: $count<br>";
}

$count=0;
start();
see();
$count++;
?>

shows:

int(0) Here: N

where N is the correct current value of $count.  Note that if I put global after session_register, it works OK.

Session variables are not in the global namespace unless specified.  This is the correct behavior.

What do you mean "unless specified"? Did you look at the code:

function start() {
                            global $count;
// If *this* is not specification of global, what is?
                            session_start();
                            session_register("count");
                            var_dump($count);
// Which "count" is 0 here? If global, why it isn't 0 below?
// If local, what happened to "global" $count I just defined and
// how do I specify that I want *that* *global* count, and not 
// want to create new local one to override old one? 
                           }

function see() {
                            global $count;
                            print "Here: $count<br>";
// And *how exactly* I got the right value here if session variable wasn't global?

                            }

Has there been any progress on this bug?
 [2000-08-15 09:38 UTC] waldschrott@php.net 
This is a dup.
 [2000-08-15 10:28 UTC] waldschrott@php.net 
duped out 6161, following code doesn?t behave equally (register_globals=on)

function increment_0() {
  global $a;
  session_start();
  $a += 1;
}

function increment_1() {
  session_start();
  global $a;
  $a += 1;
}

Note, the manual says:
"If both track_vars and register_globals are enabled, then
the globals variables and the $HTTP_SESSION_VARS entries
will reference the same value."
Thus a variable made global a before session_start()?s
should be updated accordingly

Fixed in CVS.
