Bug Type: *Session related
Description: Array stored in session loose content
Every call to the update function in the session class appends a new C_CART_ITEM with the actual
time to the cart1 and cart2 arrays.
If you reload the page several times, you get the following:
SESSION-ID: 970efca9d3effdadf14e679d0e88b349
ITEMS:
973150040 : 1 973150036 : 8
: 1 973150038 : 7
: 1 973150039 : 6
: 1 973150039 : 5
: 1 973150039 : 4
: 1 973150040 : 3
: 1 973150040 : 2
: 1 973150040 : 1
The left two rows show the content of cart1 and the right 2 rows the content of cart2. Both arrays
should have the same content.
cart1 is referenced by item in the show function. And when this is done, this entry is not available
in the next page (after reload etc.).
cart2 is referenced as the whole array - this works.
This bug occurs with PHP versions > 4.0.3 (4.0.2 not tested).
It works fine with version 4.0.1pl1 .
