Witryna27 lis 2014 · None of the STL containers is thread safe, so std::set in particular isn’t. In your case, the issue isn’t even really thread safety, though: You simply share an object across multiple threads (fine) and modify it in one thread (fine as well). But as you’ve already said, modifying the container invalidates its iterators.
