workaround:

sudo ss -Hnp -o state established 'dport = 22' src 127.0.0.1 dst
127.0.0.1 | cat -

by not trying to control terminal WIDTH, segfault does not occur.

Bug description:
  When in Ubuntu Bionic, if one calls:

  $ sudo ss -Hnp -o state established 'dport = 22' src 127.0.0.1 dst 127.0.0.1
  tcp              0                    0                                   
127.0.0.1:58910                             127.0.0.1:22               
users:(("ssh",pid=11672,fd=3)) timer:(keepalive,119min,0)

  it works. Just like when in Groovy:

  $ sudo ss -Hnp -o state established 'dport = 22' src 127.0.0.1 dst 127.0.0.1
  tcp               0                    0                                  
127.0.0.1:58908                             127.0.0.1:22               
users:(("ssh",pid=1488591,fd=3)) timer:(keepalive,119min,0)

  but.. if there is nothing to show, in Bionic we get a segfault:

  $ sudo ss -Hnp -o state established 'dport = 22' src 127.0.0.1 dst 127.0.0.1
  Segmentation fault
