      exit app will result core dump.

      when debuging, it will report corrupted double link list, or free(): chunks in smallbin corrupted

      the test code is minimized to reproduce it.

      looks like the root cause is: multiple GraphsView use the same axisX.

      it is not raised every time, but very easy by running script.

      test env: ArchLinux + KDE
