g_ptr_array_sort crash

[Gyözö Both <gyboth bygfoot com>]

hi,

i'm sorting a pointer array and every once in a while i get a segfault.
i'm checking the pointers before sorting with
g_ptr_array_sort_with_data, and they are fine. the data i pass, an
integer (with GINT_TO_POINTER) is also all right.

the crash happens in the compare function, which looks like this:

gint
player_compare_func(gconstpointer a, gconstpointer b, gpointer data)
{
    const Player *pl1 = *(const Player**)a;
    const Player *pl2 = *(const Player**)b;
    gint type = GPOINTER_TO_INT(data);
        ....
        (compare the structs that are pointed to)
        ....
}

i print out the two pointers pl1 and pl2, and mostly they are fine, but
sometimes one of them looks weird (0x049) and is obviously invalid, so
i get a segfault when the function tries to access the struct members.

as i said, the pointers in the array are all valid and ok before i call
g_ptr_array_sort.

i don't have a clue what the problem could be :-( hope you have ideas.
