説明

Currently the Leak Sanitizer (within clang v5.0.1) detects issues in node core (unrelated, as far as we can tell) to the code in node-cpp-skel.

Previously we have added default suppressions to avoid these (while keeping the option open for LeakSanitizer to detect leaks in user code).

I just removed these to confirm the node core errors still exist: https://github.com/mapbox/node-cpp-skel/commit/2072ebfed81c890fbae1ed9eab3a66627a15b1db

What should we do?

The current errors are https://travis-ci.org/mapbox/node-cpp-skel/jobs/371196767#L896

調査の方向性

まず、コミット 2072ebfed81c890fbae1ed9eab3a66627a15b1db の抑制に関する変更を、リンク先の Travis ジョブの LeakSanitizer 出力と比較します。ユーザーコードのリーク検出を維持しながら node core のレポートを除外する方法を特定します。CI ジョブが、ユーザーコードにおける関連するリークを隠蔽せずに成功すれば完了です。
