Title: Bun runtime segfault crashes claude-vscode after long-running session (v2.1.229)
Environment:
- claude-code version: 2.1.229 (cc_entrypoint=claude-vscode)
- Bun v1.4.0 (8bb8d04c4)
- Windows 11 x64 (build 10.26200), CPU features: sse42 avx avx2 avx512
What happened:
After a long-running session (elapsed ~12,505,445ms / ~3.5h; RSS 0.49GB, peak 0.54GB), the bundled Bun runtime segfaulted on the main thread and killed the CLI process:
panic(main thread): Segmentation fault at address 0x1DA184D4020
oh no: Bun has crashed.
Bun's own crash reporter produced this report link:
