Hi, All

I have an UI Application with a map widget, I create some icon overlays and one bubble overlay on the map. 

I am trying to delete these overlays in an button’s click callback, the app crashed while call elm_map_overlay_del(), post the crash log here, hope the expert can help me to solve this issue. Thank You !!!

Eina_List *list;
Elm_Map_Overlay *data;

list = elm_map_overlays_get(ad->map);
if(list) {
    EINA_LIST_FREE(list, data) 
    elm_map_overlay_del(data); 

log:
