Hey!

Can you give some more information when the segmentation fault happens? I can't seem to reproduce this for either dev or build.

[NormandoHall]

Hi @RobinMalfait

Segmentation occur at the beginning of build or dev. But if comment the @tailwindcss/vite plugin, no segmentation fault:

import { sveltekit } from '@sveltejs/kit/vite';
import { defineConfig } from 'vite';
import tailwindcss from '@tailwindcss/vite';

export default defineConfig({
	plugins: [
		// tailwindcss(), 
		sveltekit()
	]
});

Remember that it is an old OS (Centos 7) using Node 22 glibc 2.17 from https://unofficial-builds.nodejs.org/download/release/v22.13.1/

Maybe some issue with it?
