tesseract r552 1bppIndexed image error

1bppIndexed image -> AccessViolationException

Solution  in ccmain->output.cpp->

void Tesseract::write_results(                    //write output
				  ETEXT_DESC *monitor,
				  WERD_RES *word,     //word to do
				  BLOCK *block,       //block it is from
				  ROW_RES *row,       //row it is from
				  const STRING &text, //text to write
				  const STRING &text_lengths) {.....}

this function calls for 3 times "ocr_append_char" function but it use "pix_grey_" variable.
if you change it "pix_grey_" to "pix_binary_", the error improves
