Error: Failed to initialize the compiled Wasm binary with Wizer

Reproduisez l’échec avec la commande jco componentize indiquée et les entrées JavaScript et WIT de cowsay. Commencez dans jco/node_modules/@bytecodealliance/componentize-js/src/componentize.js, au niveau de l’appel signalé vers la ligne 261, puis examinez les sources de débogage de Wizer et la backtrace afin d’identifier pourquoi l’initialisation déclenche un trap. Le travail est terminé lorsque la commande s’exécute correctement ou signale clairement l’échec sous-jacent avec un test de régression.

Hi, I'm getting a wizer error when trying to use jco. This is a continuation of troubleshooting of https://github.com/bytecodealliance/StarlingMonkey/issues/15#issuecomment-2350455813. In jco/node_modules/@bytecodealliance/componentize-js/src/componentize.js, I turned on debugging.

const DEBUG_BINDINGS = true;
const DEBUG_CALLS = true;

I pushed the output debugging sources to https://github.com/cataggar/StarlingMonkey15/tree/main/b0c26fbad66e
