I am using valgrind 3.15 and 3.17. I am running valgrind in a job in a gitlab-CI pipeline and I want the pipeline to fail, if there are any leaks or memory problems.
I can show it on ls, which is leaky:
$ valgrind --leak-check=full --show-leak-kinds=all --track-origins=yes --error-exitcode=1 ls && echo no failure

What am I doing wrong? Do I miss any configuration? Does it have any hidden rule? (like the leaks should be shown, but they are).
CodePudding user response：
By default, only definite and possible leaks are considered as errors. You can use e.g. --errors-for-leak-kinds=all to have all leak kinds considered as errors:
--errors-for-leak-kinds=kind1,kind2,.. which leak kinds are errors? [definite,possible] where kind is one of: definite indirect possible reachable all none
