New issue 595 by chef...@gmail.com: Crashbug in tesseract 3.0.1
http://code.google.com/p/tesseract-ocr/issues/detail?id=595
Using tesseract with custom OCRB training to decode ID cards and passports
machine readable zone (MRZ). Usually works well except for a few particular
cases (decoding ~ 50000 images triggered this bug a few times)
What steps will reproduce the problem?
tesseract /tmp/char.bmp tmp -l ocrb -psm 10 && cat tmp.txt
Tesseract Open Source OCR Engine v3.01 with Leptonica

What is the expected output? What do you see instead?
What version of the product are you using? On what operating system?
