vitest and isolted-vm incompatible?

[ludusrusso]

I'm having some problems running isolated-vm inside a vitest test after upgrading to node 20.

With node 18.x it works well, after switching to node v20 I have a segmentation fault [1] 2778 segmentation fault pnpm run test

Quite sure this is releated with --no-node-snapshot but it seems it is incompatible with vitest.
I've read the docs of vitest and it seems is not possible to de-opt from vitest js vm.

This is what happens when I run vitest with NODE_OPTIONS=--no-node-snapshot

Error: Initiated Worker with invalid NODE_OPTIONS env variable: --no-node-snapshot is not allowed in NODE_OPTIONS

This is a bug in vitest. They should not be naively passing NODE_OPTIONS into Worker like this. If you can somehow delete process.env.NODE_OPTIONS then it will probably work. Or you can run vitest via: node --no-node-snapshot node_modules/vitest/dist/cli-wrapper.js. But I think you might run into more problems.
