List of bugs found by compiling our library in void-safe mode.
EiffelTime
- Possible call on void target found in
{DATE_TIME_PARSER}.parse.code.item (i).count_maxwas called but from the "if" clause followed,code.item (i)could be void.
if has_seps then pos2 := find_separator (s, pos1) else pos2 := (pos1 + 'code.item (i).count_max' - 1) * -1 end extract_substrings (s, pos1, pos2) pos2 := abs (pos2) if code.item (i) = Void then pos1 := s.count + 1 else ... end
WEL
- Call on Void target found in
{WEL_TREE_VIEW}.insert_itembecause there is no guarantee that `user_tree_view_item' will be attached in `an_item':
insert_item (an_item: WEL_TREE_VIEW_INSERT_STRUCT) -- Insert `an_item' in the tree. require exists: exists an_item_not_void: an_item /= Void an_item_exists: an_item.exists local l_user_item: WEL_TREE_VIEW_ITEM do last_item := {WEL_API}.send_message_result (item, Tvm_insertitem, to_wparam (0), an_item.item) an_item.tree_view_item.set_h_item (last_item) an_item.'user_tree_view_item.set_h_item (last_item)' ensure new_count: count = old count + 1 end
- Call on Void target found in
{WEL_MSGBOXPARAMS}.make_by_id, the code protected against `a_window' being Void but then in the final call still used `a_window' instead of the computed `handle':
if a_window /= Void then handle := a_window.item else handle := default_pointer end structure_make cwel_msgboxparams_set (item, 'a_window.item', a_main_arguments.resource_instance.item, a_wel_string1.item, a_wel_string2.item, a_style, cwin_make_int_resource (an_id), cwin_make_lang_id (a_language, a_sublanguage))
