Subsystem
internal/deps/v8/tools/
What steps will reproduce the bug?
$ ./node --expose-internals --eval "require('internal/deps/v8/tools/arguments')"
$ ./node --expose-internals --eval "import('internal/deps/v8/tools/arguments')"How often does it reproduce? Is there a required condition?
Always on main.
On v24.11.1 attempt to import these throws SyntaxError.
What is the expected behavior? Why is that the expected behavior?
No crash.
What do you see instead?
$ ./node --expose-internals --eval "require('internal/deps/v8/tools/arguments')"

await Promise.allSettled(require('node:module').builtinModules.filter(name => !name.startsWith('internal/deps/v8/tools/')).map(name => import(name))) with --expose-internals throws errors and effectively makes process unusable, but does not abort.
