I don’t know how those bugs get there in the first place.
Easy to explain.
Visualizing program code as cables, this is how a shiny new program would look:
And this how, for example in a commercial environment, or if the programmers are not absolute masters, such a program will look after 15 years of bug fixing, feature requests, urgent changes, deadlines, and unfinished restructurings:
The thing is that especially C code contains tons of implicit invariants which you simply cannot maintain in such code.
And don’t forgot that the picture above shows perhaps 500 cables, but a codebase can easily contain 50000 lines of code…

50K? You kidding me? Our shitty shopping cart application is 300K lines of code plus html/css
It’s mostly php
