libnest build causes segmentation fault exclusively on GNU/Linux systems (Alpine Linux is not affected)

[joshunrau]

When attempting to build even the simplest app (see below), running libnest build segfaults, exclusively on GNU systems. Despite this, verything in the build script runs successfully, and the generated code runs with (seemingly) no issues.

This occurs on both amd64 and aarch64, with Node 22.11, 22.14, and 23.10. There is no issue on Alpine Linux or MacOS.

app.ts

import { $BaseEnv, AppFactory } from '@douglasneuroinformatics/libnest';
import { Module } from '@nestjs/common';

@Module({})
class AppModule {}

export default AppFactory.create({
  envSchema: $BaseEnv,
  imports: [AppModule],
  prisma: {
    dbPrefix: 'data-bank'
  },
  version: '1'
});

libnest.config.ts

import * as path from 'node:path';

import { defineUserConfig } from '@douglasneuroinformatics/libnest/user-config';

export default defineUserConfig({
  build: {
    outfile: path.resolve(import.meta.dirname, './dist/app.js')
  },
  entry: () => import('./src/app.js')
});

Command

> rm -rf dist && libnest build -c libnest.config.ts --verbose
