I watched this talk now:
Kostya Serebryany "Sanitize your C++ code"
https://www.youtube.com/watch?v=V2_80g0eOMc
It's pretty interesting. He presents 4 sanitizers:
address, thread, memory and undefined behaviour
sanitizers. He presented them in that order. My only
complaint would be with that order. I would have
preferred to have the thread sanitizer as last. That's
because I'm more interested in the other sanitizers.
And most of the questions and comments at the end were
interesting.
