Could you please upload 000042_ocr.png here? It is created by ocrmypdf and should be somewhere in /tmp.

I cannot reproduce the issue. It works for me without any problem. Could you please add the output from tesseract --version?

Anything I can do to help reproducing the crash?
It kind of looks like this is related to the language model, maybe my model is broken?

[stweil]

Why do you think that the model might be broken? Is it an offical one? Where did you get it from? How did you install it? Maybe you can upload it somewhere.

Of course you can also try a local debug build of tesseract and get a stack trace with debug symbols.

[stweil]

Update: I can reproduce the crash with tessdata/deu.traineddata. It does not occur if you add the option --oem 1, so it is related to the old legacy OCR engine.

[stweil]

The next release 5.3.1 will include a fix for this bug (see pull request #3996). Thank you for your report!
