Isn't that basically all C/C++ code? Admittedly I don't have much exposure to it, but it's pretty much a trope in and of itself, along with Java and C# suffering from the opposite problem.

Such a silly issue too, you'd think we'd have come up with some automated wrangling for this, so that those experienced with a codebase can switch over and see super short versions of identifiers, while people new to it all will see the long stuff.
