It seems like the right tool for this problem.  What I need is a stack trace 
from a crash.

Is there a reasonable way to get a stack trace from a signal handler?  All I 
need is the number of the syscall that is getting trapped.

Or for a running program to take a core dump so I can look at it later on?  I 
haven't managed to get one out of systemd.

gdb /usr/local/sbin/ntpd
break main
run -n -u ntp:ntp

For me, on ARM, that crashes before it gets to the breakpoint.

These are my opinions.  I hate spam.
