* test/break-loader.c (randomly_set_extreme_ints): add test that sets really huge and small integers * dbus/dbus-marshal.c (_dbus_marshal_validate_arg): add check that length of boolean array fits in the string, and that string has room for boolean value in single-bool case. * dbus/dbus-message-builder.c (_dbus_message_data_load): add optional value to "ALIGN" command which is what to fill the alignment with. * test/data/valid-messages/no-padding.message: add regression test for the message padding problem
