    🚧 At least one of the CI tasks failed. Debug: https://github.com/bitcoin/bitcoin/runs/33490765972

    Try to run the tests locally, according to the documentation. However, a CI failure may still happen due to a number of reasons, for example:

    • Possibly due to a silent merge conflict (the changes in this pull request being incompatible with the current code in the target branch). If so, make sure to rebase on the latest commit of the target branch.

    • A sanitizer issue, which can only be found by compiling with the sanitizer and running the affected test.

    • An intermittent issue.

    Leave a comment here, if you need help tracking down a confusing failure.

    Grrr!! Another NOLINTNEXTLINE suppression covering up a real(ish) bug :(. Thankfully it’s just a test.

    It looks like DEBUG=1 has an effect on this?

    Maybe just enable it for the two GHA macOS tasks, which do not have DEBUG=1 enabled and also do not have sanitizers enabled?

    @dergoegge want to rebase here and make those changes?

    the two tasks are not running in docker, so the change here has no effect
