Bug#226459: gcc returns "... might be used uninitialized in this function" where it shouldn't

[Christian Neumair <chris@gnome-de.org>]

Package: gcc-3.2
Version: 3.2.3-9
Severity: minor

Unfortunately I wasn't able to track down this issue.
The code snippet in question is from the nautilus package:

=== beginning ===
static gboolean
select_range (NautilusIconContainer *container,
              NautilusIcon *icon1,
              NautilusIcon *icon2)
{
        gboolean selection_changed;
        GList *p;
        NautilusIcon *icon;
        NautilusIcon *unmatched_icon;
        gboolean select;
                                                                                
        selection_changed = FALSE;
                                                                                
        unmatched_icon = NULL;
        select = FALSE;
        for (p = container->details->icons; p != NULL; p = p->next) {
                icon = p->data;
                                                                                
                if (unmatched_icon == NULL) {
                        if (icon == icon1) {
                                unmatched_icon = icon2;
                                select = TRUE;
                        } else if (icon == icon2) {
                                unmatched_icon = icon1;
                                select = TRUE;
                        }
                }
                                                                                
                selection_changed |= icon_set_selected
                        (container, icon, select);
                                                                                
                if (unmatched_icon != NULL && icon == unmatched_icon) {
                        select = FALSE;
                }
                                                                                
        }
=== (...) snap ===
}
=== end ===

gcc returns:
nautilus-icon-container.c: In function `handle_icon_button_press':
nautilus-icon-container.c:1768: warning: `selection_changed' might be used uninitialized in this function

obviously it actually IS always initialized

Do you need any additional information?
