You're driving the builds with CMake 3.7 which still generated code on which gcc 8 warns. CMake 3.11 has the fix. If you drive with that or higher instead then the warnings should go away. OK. The issue was I keep ctest-3.7.2 (and cmake-3.7.2) first on my PATH because I want to make sure to test those versions for the PLplot case (since that is the PLplot minimum version of CMake for now although I plan within a year or so to bump that to 3.12.3 or higher once most Linux distributions provide that version). To fix this issue, I left my PATH the same but I now use the explicit system version of ctest (3.12.3 on Debian Buster) to launch the script, and the script automatically figures out inside to use the compatible version of cmake to launch other parts of the test rather than cmake-3.7.2 from my PATH). And as you predicted the warnings go away (see the most recent merlin results on the dashboard). So thanks very much for your key help in getting this issue figured out. I seem to have been the only one currently who has tried to use a ctest version less than 3.11 to drive testing, but nevertheless, you may still want to document that the minimum ctest version to drive testing should be 3.11 to avoid others running into this issue in the future.

OK, and thanks for that info. I have therefore changed the subject line appropriately. I don't notice any other platform on KWSys dashboard that also has the 8 build warnings, but it is likely my fairly recent gcc compiler (Debian Buster ccache and gcc/g++ 8.2.0) is more sensitive to problematic code in KWSys than prior versions of the gcc compiler suite. I run gcc 8.2 on castor, but I don't know why this does not trigger these warnings. It's possible it is the gcc/g++ flags I am using, but in any case someone knowledgeable should look at those build warnings which repeatedly show up on the "merlin" report for the the KWSys dashboard to see if there is anything obvious that can be done to deal with the source code issues that gcc/g++ has discovered for my Debian Buster platform.
