    • - QtCreator 4.8.0 (from online installer)

      - libstdc++ version 6.0.25 (gcc version 8.2.1)
    • Linux/X11

      After the update to QtCreator 4.8.0, the clang backend is completely broken. No matter what cpp file I open, even extremly basic files containing only a single, empty void function, cause the crash. This happens repeatedly until I close the file again. I was able to capture a stacktrace, but it does not look very useful...
