There was a problem hiding this comment.
Just ->best_choice && ... is ok.
…eract-ocr#4448) Previously if page_res_it.word()->best_choice == nullptr, dereferencing it in page_res_it.word()->best_choice->permuter() caused a segmentation fault. By checking best_choice != nullptr, i.e. there is a dictionary word, before dereferencing it, the crash is avoided. Signed-off-by: Sebastian Rasmussen <sebras@gmail.com>

Aha! I'm not well versed in C++, so I just looked at nearby code and used their NULL-checks. I'll fix it in a jiffy. :) |
