I tested the nightly versions between 19 and 20, and they both work. This succeeds:

docker run --rm -w /app node:22.20.0-alpine3.22 sh -c 'npm init -y >/dev/null && npm i @swc/core@1.13.20-nightly-20250927.1'

cc @kwonoj I think this is a bug of postinstall script?

cc @kwonoj I think this is a bug of postinstall script?

Doesn't look like it. See #11126 (comment). The binary itself segfaults.

I have exactly the same issue on MacBook.

Note that 1.13.19 installs just fine

macOS: Sequoia 15.6.1 (24G90)
2,4 GHz 8-Core Intel Core i9 32GB

Was reproducible on both nodejs 20 and 22

Spotted also on node docker image (Debian based) on ARM machine

1.13.19 works, 1.13.20 is getting SEGFAULT error code 139

[kwonoj]

@kdy1 Don't think it's postinstall script issue, #11126 (comment) shows it as well - install the musl bin directly and inovking it segfaults without postinstall script

[kdy1]

latest on npm is now 1.13.5.

• v1.13.5 is the latest on npm because of unknown build issues #11129

[hitmands]

Confirmed here.

We're having the same issue when running the install in a node alpine image (node:22.19.0-alpine) using DinD.
