I am running a robotic application on Ubuntu16. The application is compiled
with Clang's UndefinedBehavior sanitizer with an "-g" option. I got a brief
error message which seemed to indicate a bug somewhere:

My guess is that the bug is from my application, not from the more mature
QT. How could I determine which line in the source (which I can access) of
the application that triggers this runtime error?
