On Emscripten, function pointer casts can result in runtime failures due to strict function signature checks. This affects the use of g_list_sort and g_slist_sort, which internally perform function pointer casts that are not supported by Emscripten. To avoid these issues, g_list_sort_with_data and g_slist_sort_with_data should be used instead, as they do not rely on function pointer casting.
