clazy-standalone: ../clang/lib/Tooling/Core/Diagnostic.cpp:28: clang::tooling::DiagnosticMessage::DiagnosticMessage(llvm::StringRef, const clang::SourceManager &, clang::SourceLocation): Assertion `Loc.isValid() && Loc.isFileID()' failed.
02:01:55: Error: Failed to analyze 1 files.
02:01:55: Clang-Tidy and Clazy finished: Processed 0 files successfully, 1 failed.
02:01:55: Elapsed time: 00:02.

The proposed patch fixes the issue. DiagnosticMessage indeed received an empty and invalid file location from a macro location. Checking for a macro location now allows DiagnosticMessage to receive a proper file location from an eventual returned macro expansion location.
