That’s not a segfault, that’s a bus error, which also refers to memory, but it’s a different kind of error, typically occurring when you access a misaligned address or some address which cannot possibly be referenced. Probably a problem with one of the pre-built binaries some npm module ships

I had this issue with sveltekit trying the host option of vite running with bun.
The solution was to re-do the lock files.
You have to delete them and the node_modules folder.
Then you can npm install.

Reprogram in vanilla js html and css - > No dev server. No problem.
