Oops, I really misunderstood your note, and re-reading it now I can't really understand why. I thought you were saying it was fixed, but really you were saying it is still there and should be fixed if we want to support GCC 6.4. I am not sure if we should try to fix it or not. Locally I plan to disable unit tests on this particular machine. It is the only one using 6.4. Tom
