This warning can be seen with GCC 15.2:
mptcp_connect.c: In function ‘main_loop’:
mptcp_connect.c:1422:37: warning: ‘peer’ may be used uninitialized [-Wmaybe-uninitialized]
1422 | if (connect(fd, peer->ai_addr, peer->ai_addrlen))
| ~~~~^~~~~~~~~
mptcp_connect.c:1377:26: note: ‘peer’ was declared here
1377 | struct addrinfo *peer;
| ^~~~
This variable is set in sock_connect_mptcp() in some conditions. If not,
this helper returns an error, and the program stops. So this is a false
positive, but better removing it by initialising peer to NULL.
