A program is ending with a segmentation fault, apparently there's a core dump of it, however it isn't in the cwd.
`cat /proc/sys/kernel/core_pattern` returns
/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %h %e
Where does systemd-coredump output the coredump to?

How to post. A sincere effort to use modest and proper language and grammar is a sign of respect toward the community.

Does this gdb backtrace suggest that not all of the params I specified had been sent to echoping?
echoping -w 1 -p 6 -t 1 -6 -m /usr/lib/echoping/dns.so -n 20 facebook.com -t AAAA --tcp facebook.com

Core was generated by `echoping -w 1 -p 6 -t 1 -6 -m /usr/lib/echoping/dns.so -n 20 facebook.com -t AA'.
Program terminated with signal SIGSEGV, Segmentation fault.

But if I run the partial command shown in gdb I get:

So not sure what to believe.
