Description

Codex CLI intermittently crashes while executing tasks on Windows. This has happened multiple times during normal task execution.

Immediately before the process terminates, the terminal displays:

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

### What steps can reproduce the bug?

The issue is intermittent, but the general sequence is:
1. Start Codex CLI from PowerShell.
2. Ask Codex to execute a task involving multiple file or shell operations.
3. Allow the task to run for some time.
4. Codex CLI unexpectedly panics and terminates.
5. The terminal prints the RUST_BACKTRACE=1 message.
I have not yet identified a single command that reliably triggers the panic.

### What is the expected behavior?

Codex CLI should either complete the task or report a recoverable command/tool error without terminating the entire session.

**Actual behavior**
The Codex CLI process panics and exits, interrupting the active task.

### Additional information

The problem has occurred multiple times rather than as a one-time failure. Please let me know if a full backtrace, diagnostic report, session log, or additional environment information would be helpful.

Start Codex CLI from PowerShell on Windows and exercise the described multi-file or shell-operation workflow. Collect a full RUST_BACKTRACE, diagnostic report, or session log when the intermittent panic occurs; done means the task completes or reports a recoverable command/tool error without terminating the session.
