Is it possible to use Valgrind or other memory leak detector to debug native Node.js addons?

[VictorQueiroz]

I use Valgrind to detect memory leaks in my C/C++ code so I'm wondering if it'd be possible to do the same to my C++ code that I write to create bindings to my Node.js code. Downloading Node.js from source and building it with debug flag and then using Valgrind would be a reasonable option?

Also would be possible to integrate it with IDE like CLion? It'd definitely be something else.

Thank you in advance.

You can and you probably don't even need to build Node.js in debug mode, just your add-on. Pass --debug to npm or node-gyp.

There's a suppression file but it's best effort and against master, it might not work (fully) against release versions.

I don't know about IDE integration, I don't use those.

Don't know about IDE integration either, but I can confirm that I've used valgrind with Node.js and addons (for example in nodejs/node#26667). I did use --debug but even without that I got useful data.
