c4f6077994Use a fixed random seed to ensure that the generated sources are identical across runs. The final node binary still reseeds itself on start-up so there should be no security implications caused by predictable random numbers (e.g., `Math.random()`, ASLR, the hash seed, etc.) Fixes: https://github.com/nodejs/node/issues/29108 PR-URL: https://github.com/nodejs/node/pull/29142 Reviewed-By: Gus Caplan <me@gus.host> Reviewed-By: Colin Ihrig <cjihrig@gmail.com> Reviewed-By: Anna Henningsen <anna@addaleax.net>
