tailwindcss core dump on Ampere Arm

I was recently deploying a rails app on an Ampere Arm instance which used Tailwind 4.1.18. During the rails assets precompile build step, tailwindcss failed with:

Command failed with SIGABRT (signal 6) (core dumped): /usr/local/bundle/gems/tailwindcss-ruby-4.1.18-aarch64-linux-gnu/exe/aarch64-linux-gnu/tailwindcss

I didn't dig into it much further to figure out why, but searching around I did not find any more reports of this problem. I did find a workaround, which was to build with the node version of tailwind instead. My deployment was all in Docker, so I first added these environment variables to point the tailwindcss-ruby gem at the node executable:

 TAILWINDCSS_INSTALL_DIR=/rails/node/node_modules/.bin \
    NODE_PATH=/rails/node/node_modules \

Ensure npm is installed via apt-get and add the following step to the docker image build:

RUN mkdir /rails/node; npm install --prefix /rails/node tailwindcss @tailwindcss/cli
...
RUN bundle exec bootsnap precompile --gemfile
...
# Cleaning up the tailwindcss workaround
RUN rm -rf /rails/node

After that, the build worked fine.
