Codex doctor report

  "overallStatus": "ok",

  "platform": "linux-x86_64"
}

What issue are you seeing?

When I run Codex CLI on a remote Linux server over SSH, the local Terminal.app intermittently crashes and relaunches.

This occurred seven times between August 10 and August 18, 2026. The macOS crash reports identify Terminal.app as the crashing process. Representative signatures include nanov2_guard_corruption_detected, CoreText SIGTRAP, and AppKit EXC_BAD_ACCESS.

What steps can reproduce the bug?

1. Open Terminal.app on macOS.
2. SSH into a Linux server.
3. Start Codex CLI normally.
4. Use Codex interactively for an extended session.

The crash is intermittent and is not associated with a specific prompt.

What is the expected behavior?

Codex CLI should run over SSH without crashing the local Terminal.app process.
