Original GitHub issue: https://github.com/anomalyco/opentui/issues/58

Environment

MacOS Sonoma v14.6
Ghostty v1.1.3
Bun v1.2.18
React v19.1.1
@opentui/core v0.1.8
@opentui/react v0.1.8

Overview

Bun encounters a segfault when attempting to set selectedDescriptionColor in the <tab-select /> component. Error below:

Anecdotally, once the program crashes, the terminal continues to track my cursor movements and prints out semicolon-delimited codes that look like vector positions at first glance. Not sure if that helps diagnosis, but worth noting:

Steps to reproduce

Create a new Bun project mkdir example && cd example && bun init -y
Install deps bun add @opentui/core @opentui/react react
Save the below file as tab-select-example.tsx
Run: bun run tab-select-example.tsx
Observe the crash
Remove or comment out selectedDescriptionColor and run again
Observe it runs as expected

Test file

import { render } from "@opentui/react";

export const Test = () => {
  const tabOptions = [
    { name: "One", description: "tab one", value: "one" },
    {
      name: "Two",
      description: "tab two",
      value: "two",
    },
  ];

  return (
    <tab-select
      options={tabOptions}
      style={{
        selectedDescriptionColor: "#cccccc",
      }}
    />
  );
};

render(<Test />);
