+  File 'cpp11tesseract/libs/x64/cpp11tesseract.dll':
+    Found symbols like 'std::cerr', 'abort', 'exit', 'rand', etc.
+
+  This only affects R 4.5.0 on Windows. These symbols appear in the DLL because
+  they are part of the underlying Tesseract and Leptonica static libraries. Our
+  package code does not call these functions, but they are unavoidably included
+  when statically linking against these third-party OCR libraries.
