Valgrind Memory check complains on TessBaseAPI

Working on memory leaks, just faced that valgrind memcheck sees serious leak on TessBaseAPI initialization call.

Update: official Tess Sample gets warning from valgrind https://tesseract-ocr.github.io/tessdoc/Examples_C++.html

api4->Init

is there any way to fix this?

 void Name::test(){
tesseract::TessBaseAPI *apiUnique = new tesseract::TessBaseAPI();
apiUnique->Init("/usr/share/tesseract-ocr/4.00/tessdata/", "eng");
outText = apiUnique->GetUTF8Text();
apiUnique->Clear();
apiUnique->End();

delete [] outText;
delete  apiUnique;

}
