Environment

Current Behavior:

Hi.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=906922

Package: tesseract-ocr Version: 4.00~git2844-607e8fd8-2 Severity: normal

Hi,

I've got a coredump on running tesseract. If it helps, I can provide the image, but I could reproduce this behaviour with different images.

Here are the details of the crash:

Please test with latest code. This issue should be fixed by PR https://github.com/tesseract-ocr/tesseract/pull/1818

AlexanderP commented 6 years ago

@Shreeshrii Absolutely right, last code does not have this error. i uploaded in mentors.debian.net

amitdo commented 6 years ago

For 4.0 betas released before that patch this command should solve the issue:

tesseract -l osd --psm 0
