lcm_get_fileno returned invalid (bad) fd upon start
See the log at https://travis-ci.com/lcm-proj/lcm/jobs/286003862

setsockopt (IPPROTO_IP, IP_ADD_MEMBERSHIP): Bad file descriptor
fatal error: unexpected signal during runtime execution
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x7fff62fb86cf]

The test is "fixed" by a short startup delay (1s) but this should still probably be fixed.
Have not looked deeper into the causes of this than the fact that its in LCM core and not the go wrapper.
