Leak demonstration program

Here's the output on current trunk:

          86        2548
          87        2548
          88        2548
          89        2548
          90        2548
          91        2548
          92        2548
          93        2548
          94        2548
          95        2548
          96        2548
          97        2548
          98        2548
          99        2548
         100        2548

Same output with gcc 9.

So, I think the advice would be to upgrade to gcc 9.
