Recent gcc started tracking this and now it's warning:
test_1_to_1_connectx.c: In function ‘main’:
test_1_to_1_connectx.c:133:17: warning: array subscript ‘struct sockaddr[0]’ is partly outside array bounds of ‘unsigned char[15]’ [-Warray-bounds]
133 | tmp_addr->sa_family = AF_INET;
| ^~
test_1_to_1_connectx.c:132:40: note: referencing an object of size 15 allocated by ‘malloc’
132 | tmp_addr = (struct sockaddr *) malloc(sizeof(struct sockaddr) - 1);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It gets parsed by __connectx_addrsize using each family struct, but they
aligned to sockaddr size. So lets fix it here by allocating the right
size.
