Comment 0 for bug 1913187

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
