That an answer to the wrong question...

My question was about the sorting of objectClass values:
https://git.samba.org/?p=abartlet/samba.git/.git;a=commitdiff;h=c74751d5e89e9b36a0987589f4dd0e481137561d

Can you initialize alpha_sorted to NULL in the declaration we had a
number of security
bugs related to unitialized pointers already...
The code would also look much clearer if we would have:

struct class_list *unsorted = NULL;
struct class_list *sorted = NULL;
...
struct class_list *alpha_sorted = NULL;

Instead of the spaghetti:

struct class_list *unsorted = NULL, *sorted = NULL, *current = NULL,
        *poss_parent = NULL, *new_parent = NULL,
        *current_lowest = NULL, *current_lowest_struct = NULL,
        *alpha_sorted;

Ok, do we have bug reports for all this problems?
