LGTM. A note on the commit log:

adding missing header for the leak check.

We (usually) use present tense and (always) capitalize: s/adding/Add/

I'd probably also s/leak check/leak checker/, s/leak check/leak sanitizer/ or just s/the leak check/LSAN/.

A little off the topic, how do I enable asan when building Node.js ?

./configure --help should give you the answer.

@nodejs/build Is it possible to add a job to test asan build works and prevent future regression ?

I'm part of the Build WG these days so I suppose I can answer that. ^^

It's certainly possible to add a linux+asan job (this PR is about lsan though) but running the test suite is out of the question - sanitizers cause a 20-200x slowdown.

That makes it less useful because the point of course is to catch runtime misbehavior. Maybe we could run a subset of tests but I don't immediately have good suggestions on what subset that should be.

TBD whether to build with clang, gcc or both. Can you open a nodejs/build issue if you still think it's a good idea?

An additional suggestion would be to use a subset of asan checks via ASAN_OPTIONS environment variable.
