Hi
At line 1118 of src//lib-index/mail-index-map.c, inside the function mail_index_map_move_to_memory, there is: mail_index_map_copy_header(map, map);
Valgrind is stating that "Source and destination overlap in memcpy". I'm wondering if this code is just coping the same memory over itself, or if it is doing something useful.
