v12: hangs on calling console.log with large object

[pimlie]

• Version: v12.10.0
• Platform: Linux x64
• Subsystem:

Unfortunately I was unable to reproduce this with a small circular object, I think at least it has something to do with circularity, no idea what else could cause this.

Reproduction is here, this tries to log a full VueComponent: https://github.com/pimlie/node-v12-util-inspect-issue

Steps:

• clone & install
• run: node --inspect ./node_modules/.bin/nuxt
• attach debugger
• browse to http://localhost:3000
• node now hangs, webpage never loads
• If you now try to record a CPU profile it will kill node and log the error below

Tested v10.16.3 and v8.16.1 which both work fine. Possibly related to #29592?

I am looking into it. Inspection of some options is not working as intended. Seems like the prototype inspection is missing a recursion end condition.

These seem problematic:

VueComponent.$root.$options.components
VueComponent.$root.$options.directives
VueComponent.$root.$options.filters
