And FYI: Modifying superglobals is totally unsupported, so this is not
really any bug.

Do you happen to have "register_globals=On" ? (And if you think you
don't, are you sure?)

Also it's been my experience that super globals are not sensitive. I 
write to them all the time. This is just a bug.

The same problem happens with regular vars also.

The superglobals are sensitive beasts and mixing the even more special
$_SESSION will give you lot of unexpected results. Reclassified as
documentation issue as docs should express this with bigger font
(preferrably something around the size of a cat) and blinking warning on
the session/superglobals pages. 

Rule of thumb: $_SESSION is writable, the others are not!
