amd64 build works fine

Docker image

php:8.2-fpm-alpine3.20

Minimal Dockerfile

FROM php:8.2-fpm-alpine3.20

COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/local/bin/

RUN install-php-extensions saxon

It is the same for php:8.4-alpine3.22. So arm64 + alpine seam to be broken in general.
php:8.4-trixie works perfect for both platforms.

Can you check if running

apk add gcompat

fixes the issue?

Hi, just to say that there's a bug in the upstream that only seems to affect Alpine on ARM. We will ship a fix in our next maintenance release.

Installing gcompat is required, but I don't think that just installing it will be enough for a PHP module. In my testing, I needed to set the LD_PRELOAD environment var for the entire PHP process to get it to successfully load (which I have managed with a patched upstream). I'm not sure that's part of this script's responsibilities, but it does make verifying the install is set up correctly trickier.
