Google Chrome works fine with it.

This is by design and not technically possible afaik @alexeykuzmin

Node.JS itself isn't designed to have multiple instances in the same process. See #6903

We should probably just catch that flag somehow and prevent it taking effect while logging out a nice error 😄

Ok, then the question is does it crash where it's supposed to crash or not?
Added stacktrace in the description.

Makes sense 👍

[zcbenz]

We uses v8::Lock in the main process (to follow Node's convention), while the renderer process does not use it (to follow Chromium's convention). That's the reason of the crash.

[CapOM]

Does the last comment mean it is fixable ?

[codebytere]

Given that this has been open for years, that this isn't currently on our roadmap, and in the interest of our issue tracker more closely reflecting our workstreams, i'm going to go ahead and label this a wontfix. However, should someone determine a workable solution we would be potentially open to accepting a PR.
