Call stack ..-> gip_dispatch_pkt() -> gip_handle_pkt_announce() -> gip_request_identification()->gip_send_pkt(client, &hdr, NULL) leads to NULL dereference in memcpy function. Quite sure, it can't really happen in real life, but compiler spams an error: ``` bus/protocol.c:382:9: error: argument 2 null where non-null expected [-Werror=nonnull] 382 | memcpy(client->chunk_buf_in->data, data, hdr->chunk_offset); ``` This NULL check will calm down a compiler.

Sorry, I missed this PR but added something similar to my fork (dlundqvist/xone@aeb27e6). |
