I recently set out to implement a few basic data structures in C for the hell of it (and to reassure myself that I can still code C), and ran into an interesting compiler wart… I was trying to instantiate a static array of 10 million integers (who doesn’t?), in order to test insertions and deletions in my tree. However, as you can astutely deduce from the title of this post, this was too much for the stack of my poor program and ended up in a segfault - a textbook stack overflow.

During the past few weeks, I have been writing a C++ plugin to grade C41 digital intermediates in Cinelerra, an open-source Linux video editor. C41 is the most common chemical process for negatives, resulting in films that look like this â you probably know it if you’ve ever shot film cameras. Of course, after scanning those negatives, you have to process (“grade”) them to turn them back to positive. And it’s not as simple as merely inverting the values of each channel for each pixel; C41 has a very pronounced orange shift that you have to take into account.
