Apologies if this is a dumb question, but can you point me to a
procedure? My only acquaintance with backtraces is during kernel
crashes, when the backtraces is presented on the console. At this
point it's not obvious what crashed (gmake or cargo), nor where
the core file went.

Might this problem be specific to the Pi3? I thought not, but....
