Hello,I need some help understanding what might be wrong with a piece of code from the openvswitch project. By ${subject} I'm not suggesting there's a problem in gcc, clang also shows the same behavior so it's likely our code is broken. I am kindly asking for help to understand/troubleshoot the problem.
The typical approach to discovering such issues is to use address sanitizer [1] or valgrind [2]. The former is usually recommended. Optimization is not necessarily enabled.
