Hi Leo,

That looks like pretty odd behavior.  What version of PHP is it?

This may be relevant, from the PHP manual
http://www.php.net/manual/en/ref.session.php :

session.bug_compat_42  boolean
     PHP versions 4.2.3 and lower have an undocumented feature/bug that 
allows you to initialize a session variable in the global scope, albeit 
register_globals is disabled. PHP 4.3.0 and later will warn you, if this 
feature is used, and if session.bug_compat_warn is also enabled. This 
feature/bug can be disabled by disabling this directive.

session.bug_compat_warn boolean
     PHP versions 4.2.3 and lower have an undocumented feature/bug that 
allows you to initialize a session variable in the global scope, albeit 
register_globals is disabled. PHP 4.3.0 and later will warn you, if this 
feature is used by enabling both session.bug_compat_42 and 
session.bug_compat_warn.


Looks like the PHP developers agree with you, at least half-admitting 
that it's a bug.
