I was getting a Segmentation fault trying to run SWC after following the installation https://symfony.com/bundles/AssetMapperTypeScriptBundle/current/index.html

Turns out that I needed a different SWC binary due to the fact that I was using an Alpine docker container for my project.
After using NPM to install SWC including their @swc/core-linux-musl package and changing my config to use that binary instead it worked.

Oh and another note: Your documentation says that I should add "binary" to my config file. This apparently has to be swc_binary instead.
