@bertsky, it's a bit strange if you add an unrelated commit to a pull request which was already reviewed by yourself.
I am not sure that your change in line 126 is a good idea (debug code adds instructions that increase processing time), and you have not given a proper explanation of why you made it.

I'm afraid your change will do exactly what you wanted to avoid.

see this why we must at least avoid NDEBUG; keeping -g otherwise is a good idea to get symbols when there is a crash
all this is a far cry from being satisfactory (libtesseract must use exceptions in the end!), just less insane (segfault)

So you prefer getting a SIGSEGV because of your change instead of getting an abort() like in the current configuration?

in other places like this we need !defined(NDEBUG) for certain safety checks

No, segfault is obviously even worse, but I'm in a bind: the place that actually triggers my latest segfault/abort needs !defined(NDEBUG) – so the snippet I showed first behaves different, but is (currently) not as relevant

See sirfz/tesserocr#365 for how I would like this to be solved.
