The result was that on Linux (using `javascriptcoregtk-4.0`), Asan caught a few leaks: https://github.com/crossnx/includejs/actions/runs/7934077830/job/21667816487 But on macOS, the CI passes (and even locally) without catching anything: https://github.com/crossnx/includejs/actions/runs/7975463940/job/21773755192#step:7:26 I'd like to understand why there is such a difference (clang linux vs clang on macos or whatever) :) I would be more than happy to help if I may.

Can you provide details on what the supposed leak is (even if it's only on Linux).
