What's Wrong?

[Windows 11/10] CLI crashes with rapid text scrolling after extended use - possible memory leak (v2.0.72)
Body:

Environment

• Claude Code version: 2.0.72
• OS: Windows 11
• Terminals tested: CMD, PowerShell, VS Code integrated terminal (issue occurs in all)
• RAM: 32GB + 32GB virtual memory
• Session length: 10-20 hours typical

Problem Description

After extended use (never at session start, always after several minutes of work), the CLI crashes with a distinctive pattern:

1. Text starts scrolling extremely fast on screen
2. Terminal freezes completely
3. Must kill the process manually (Ctrl+C doesn't work)
4. Context is lost or corrupted

Frequency

• ~10+ crashes per 10-20 hour session
• Severely impacts productivity
• Ongoing for months across multiple versions

Behavior Details

Before crash:

• Rapid uncontrolled text scrolling
• No user input possible

After crash:

• Sometimes: can copy last visible instructions and recover context manually
• More often: session resumes with context from minutes/hours earlier or even previous sessions (context corruption)

What I've tried

• Different terminals (CMD, PowerShell, VS Code integrated) - same issue
• Adjusting virtual memory settings - no effect
• System has 32GB RAM + 32GB virtual - resources not the issue

Suspected cause

The pattern (never at start, always after extended work) suggests:

• Memory leak in the CLI process
• Context buffer overflow
• Rendering issue when context grows large

Impact

This has been happening for months and significantly affects daily work. Sessions of 10-20 hours are common for my workflow, and losing context 10+ times per session is extremely disruptive.

Request

• Investigation into memory usage over time
• Possible automatic context compaction before critical thresholds
• Better crash recovery that preserves recent context accurately

System Info

Happy to provide additional logs or run diagnostic commands if needed.

Note: I have plenty diferent machines, setups, workflows. I here to help.
