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!

Description:
------------
When you set a $_REQUEST var = a $_SESSION var and the session var
contains alot of data, reseting the session var also reset the
$_REQUEST
var.
Configured: './configure' '--prefix=/apps/php' '--with-zlib-
dir=/apps/zlib' '--enable-exif' '--with-tidy=//apps/tidy' '--enable-
track-vars' '--with-calendar=shared'
'--with-config-file-path=/apps/etc'
'--enable-pcntl' '--host=x86_64-redhat-linux' '--enable-magic-quotes'
