tesseract call abort fn

[ava57r]

Hello
tesseract cpp can call abort fn
https://github.com/tesseract-ocr/tesseract/blob/main/src/ccutil/errcode.cpp#L83

rust can not catch this call
Could We make this call more safer?
rust-lang/rust#74990

Hey

Sorry I'm only now getting round to looking at this.

I don't think there's much we can do directly. I think the mentions of abort in the rust tracker issue are different to the abort in errcode.cpp. the former is the general idea of the program quitting in regards to panics. The latter is the libc function.

What we could do is:

1. Sandbox the library using wasm. There are likely to be performance issues with that as tesseract presumably uses SIMD and threading.
2. Ask tesseract upstream to remove this call to abort. Do you have a test case that triggers this abort?

I did not catch a test case.

I caught this on production but I can not reproduce in test case

[ava57r]

I updated on v5.3.4

I found this
