LeakSanitizer suppressions #121

Open springmeyer opened 6 years ago

springmeyer commented 6 years ago

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
