        Description

        Optimization-unstable code (unstable code for short) is an emerging class of software bugs: code that is unexpectedly eliminated by compiler optimizations due to undefined behavior in the program.

         

        We applied a static checker STACK [1] to OpenJDK and found a number of such unstable code.
