• Claude CLI version: 20250807
• Operating System: Windows 11 -> WSL Ubuntu

Bug Description

Claude was checking for the existence of large files. Claude said it's the CLI runtime, so I should report it.

Steps to Reproduce

1. I downloaded several multi-GB .PTH files. There's a script to copy them into place. Claude was running something in bash to confirm that they were all in place.
2. Let me know if you need more info.

Expected Behavior

Find the files

Actual Behavior

Crash (see below)
