],How can we reproduce the crash?
Bun crashes with a segmentation fault at address 0xFFFFFFFFFFFFFFFF when running a command involving opencode.exe. This occurs on Windows x64 and is indicated as a bug in Bun, not user code. The crash happens intermittently, potentially during file operations, hot-reloading, or server/dev mode.
This seems similar to existing issues like #25798 (segfault at 0x0 with opencode-ai in Next.js), #21314 (segfault in SvelteKit dev), and #21286 (segfault in Express.js with CSS watcher). If this is a duplicate, please close and link accordingly.
Environment
- Bun Version: 1.3.5 (commit: 1e86ceb)
- OS: Windows 10
- Terminal: Warp
- Project Type: Appears to involve Node modules, VSCode integration (
node_modules\vscode-windows-x64\bin\opencode.exe), and possibly a web dev framework (e.g., React/Next.js based on args)
Steps to Reproduce
- Install Bun v1.3.5 on Windows x64.
- Set up a project with dependencies including opencode or similar AI tools (e.g., via VSCode extension).
- Run a command like:
bun run dev or execute opencode.exe with args such as --user-agent=opencode/1.1.15 --use-system-ca -- l+p.
- Perform actions that trigger file reads/writes, hot-reloading, or server operations.
- Observe the crash after some elapsed time (in this case, ~755s runtime).
(Note: Exact repro might be intermittent; happens during development workflows.)
Expected Behavior
Bun should handle the operation without crashing, continuing to run the server or script.
Actual Behavior
Bun panics with: panic(thread 21284): Segmentation fault at address 0xFFFFFFFFFFFFFFFF
Followed by: Oh no: Bun has crashed. This indicates a bug in Bun, not your code.
