yes new eng.traineddata has length 21,876,572.
I created test file (in attachment) and calling API with:
myTess->Init(NULL, "eng", tesseract::OEM_DEFAULT, NULL, 0, false);
it throw error:
test_302.cpp:22:69: error: no matching function for call to
‘tesseract::TessBaseAPI::Init(NULL, const char [4],
tesseract::OcrEngineMode, NULL, int, bool)’
test_302.cpp:22:69: note: candidates are:

If I provide 8,3 or 2 arguments it works ok...
