[BUG] Claude Code crashes after terminating spawned process

Environment

• Platform (select one):
• [X] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 1.0.73
• Operating System: macOS 15.6 (24G84)
• Terminal: Terminal App

Bug Description

When running commands that timeout, or are backgrounded that end either because Claude Code kills them, or otherwise, Claude Code crashes with a spawn error.

⏺ The script has been running for over 2 minutes, which is quite long. It seems to be stuck loading the large Excel file. Let me kill
  this process and create a more efficient version that shows better progress:

⏺ Kill Bash(Kill shell: bash_5)
  ⎿  Shell bash_5 killed


node:internal/child_process:421
    throw new ErrnoException(err, 'spawn');
    ^

Error: spawn EBADF
