The snapshot reproducibility test has been failing in dynamically linked builds since yesterday. From CI history it was still green at cd8e61f (https://ci.nodejs.org/job/node-test-commit-linux-containered/44116/), but started failing no later than 4c730ae (https://ci.nodejs.org/job/node-test-commit-linux-containered/44117/), that means either one of the two commits in cd8e61f...4c730ae caused the regression, or some infra update happened yesterday caused the regression.

Looks like 4c730ae broke the test. Opened to revert it for now to make the CI green #53582.

Reason for revert: broke test-snapshot-reproducible.js in
dynamically linked builds in the CI.

This reverts commit 4c730ae.

I haven't been able to reproduce this locally yet, but from the logs:

20:38:52     + ]

I suspect the unreproducibility comes from the hash of the flags - at least, it seems to be in the header of the main context snapshot.

I haven't been able to reproduce this in a "normal" build (Linux) but can with 4c730ae when building with configure --shared-openssl.

I am still unable to reproduce it with ./configure --shared-openssl or ./configure --with-intl=small-icu, neither on macOS nor on Ubuntu 23.04...but I could try logging into one of the containers to debug.

Ah, I could reproduce it now, it needs a separately installed shared openssl.

I can reproduce this on a local docker ubuntu container:

Locally this patch fixes it for me (it is rather curious why this only shows up in dynamically linked builds, though..): https://chromium-review.googlesource.com/c/v8/v8/+/5662576
