# Filing Bugs and Feature Requests

We encourage users to file bug reports for any problems that they encounter. We also welcome feature requests. When filing a bug report, please do the following:

- Include the checker build (for prebuilt Mac OS X binaries) or the SVN revision number.
- Provide a self-contained, reduced test case that exhibits the issue you are experiencing.
- Test cases don't tell us everything. Please briefly describe the problem you are seeing, including what you thought should have been the expected behavior and why.

## Outside of Apple

### Bugzilla

Please file bugs in LLVM's Bugzilla database against the Clang Static Analyzer component.

### Bugreporter.apple.com

If you are using the analyzer to analyze code associated with an Apple NDA (e.g., preview versions of SDKs or seed releases of Mac OS X) please file bug reports to Apple's Bug Reporter web site.

You are free to always file bugs through this website, but this option less attractive than filing bug reports through Bugzilla as not everyone who works on the analyzer has access to that bug database.

## Apple-internal Users

Please file bugs in Radar against the llvm - checker component.
