But seriously, I try to use printf's for only truly trivial things; I use various kinds of debugging tools for everything else (e.g., I'll frequently use gdb to examine corefiles and/or attach to individual processes in parallel jobs to do heavy-lifting debugging).

I use the gdb technique, too, but didn't want to suggest that and then
be on the hook for writing detailed instructions here on how to do it. :-)
