Yeah, that just SIGABRT's immediately for me just from loading my dives.
Apparently I have a dive with
ndl=71582788:15
in my dive log, because that's how we print a duration of "-1" and
we've imported an invalid ndl at some point.
So using -ftrapv actually works, but may not be practical. But for
debugging this particular issue, I'll just start with an empty dive
log and try your planner thing.
If you want to test this yourself, just do
ccmake .
in your build directory, and then go and change the optimization
options to "-g -ftrapv" and re-generate and build.
