FIXME: The `buf_addr_rec` maps to the `uint8_t *buf` field of the internal `RR_handle_packet_args` struct. The field is dumped/loaded to/from the trace without proper serialization/deserialization. As a result, a 64bit build of PANDA will not be able to process traces produced by a 32bit of PANDA, and vice-versa. There are more internal structs that suffer from the same issue. This is an oversight that will eventually be fixed. But as the real impact is minimal (virtually nobody uses 32bit builds), the fix has a very low priority in the bugfix list.
