Plugin panics on release builds

[arlyon]

Describe the bug

Hi!

I have been working to upgrade stailwc to a newer version of next but have been running into issues. I am on swc_core@0.76.9, testing against @swc/core@1.3.59 and against next@13.4.3.

I can run my plugin in debug mode no problem, however release mode causes panics. I have a repro branch here, simply build the plugin in debug and release modes and then have a look at examples/swc (updating the wasm path as appropriate in install.js).

git clone https://github.com/arlyon/stailwc.git -b repro/release-build-fail
cd stailwc
cargo build --target wasm32-wasi
cargo build --release --target wasm32-wasi
cd examples/swc
yarn
# override path to stailwc.wasm in install.js
yarn build

Input code

import { TailwindStyle } from "stailwc";

const Button = tw.button`content-[Hello World] px-4 py-2 bg-red-500 rounded-full text-white`;

export const App = () => (
  <div tw="w-screen h-screen">
    <TailwindStyle />
    <Button />
  </div>
);

Expected behavior

I expect release builds to also pass.

❯ yarn build 
$ node ./install.js > .swcrc && swc index.tsx -o index.js
Successfully compiled 1 file with swc.
Done in 1.35s.

Actual behavior

Panic.

❯ yarn build
$ node ./install.js > .swcrc && swc index.tsx -o index.js

https://swc.rs/docs/plugin/selecting-swc-core
I think @swc/core@1.3.59 and next@13.4.3 cannot be supported at the same time

@arlyon try disabling lto? wasmerio/wasmer#3764 (comment)

[arlyon]

That did it, TY! Linking the docs PR for posterity swc-project/website#220

Cool, let's close as resolved for now.
