Illegal instruction at address 0x579130D

How can we reproduce the crash?

Dunno, I was writing code like below where I missed the accumulator return at first

    const values = columns.reduce((acc, column) => {
        const value = args.input.collection[camelCase(column.name)];
        if (typeof value === "undefined") {
            return acc;
        }

        acc[column.name] = value;
        return acc;
    }, {} as Columns);

That code wasn't being executed however, the project itself is an Elysia web project that creates two https://github.com/porsager/postgres at startup, one with https://github.com/drizzle-team/drizzle-orm and the other with https://github.com/kysely-org/kysely-postgres-js

Also important could be that I was in debug mode with the Javascript Debug Terminal running on VSCode using the Bun extension.
