The analyzer does not do any cross-translation unit uniquing. So if an error is detected in the same header in multiple translation units it will get reported multiple times. Also, if the analyzer notices that the last component of path diagnostic is in a header, it will try to report the diagnostic at the last location along the path in the mail file (see PathDiagnostic::resetDiagnosticLocationToMainFile()).
