[CRIU] Looks like stack garbage could be dereferenced in collect_pstree_ids_predump()

[Batalov Eugene]

Hello.

Please take a look at ./cr-dump.c:717-742 lines:

717: struct pstree_item *item; // local pointer variable isn't initialized
explicitly
...
// First use of item is here:
734     for_each_pstree_item(item) {

// Here is how macro is defined
75 #define for_each_pstree_item(pi) \
76     for (pi = root_item; pi != NULL; pi = pstree_item_next(pi))

Looks like
struct pstree_item *item = NULL;
is needed here.
