Simple express app segfaults in alpine Docker image

[serenitus]

I have a very simple express app that runs perfectly well locally (Intel Mac, Sonoma) but segfaults when run using the latest official alpine Docker image.

Dockerfile:

FROM denoland/deno:alpine-1.38.0

EXPOSE 8080

WORKDIR /app

RUN apk add --no-cache bash coreutils grep sed

USER deno

ADD . .

CMD ["run", "--allow-all", "main.ts"]
# CMD ["--version"]

main.ts:

import express from 'npm:[email protected]';

const app = express();

Running with: docker run -d --init -it -p 8080:8080 app

deno itself runs just fine as can be seen by trying the --version command currently commented out in the Docker file or, in fact, trying any other trivial code such as console.log().

Can anyone figure out what the issue is?

I have managed to make this work with alpine-1.34.0 but haven't narrowed the issue down any further than that as yet.

Update: it broke with alpine-1.37.2

Actually, that turned out to be a bit misleading. While 1.37.2 dies immediately, 1.37.1 and 1.37.0 die after a second or too. I was misled by their fleeting presence in the docker ps list.

alpine-1.36.4 actually seems to be the last stable release.
