Of course, in the program like this. It's quite obvious that for a bigger program it would be much harder. I wouldn't use C for a big monolith system or if I had to, I would put much effort in diagnostic features.
I don't write professionaly C code. I use it for my purposes so debugging is easy. I agree that such a problem in a bigger system whithout ability to reproduce environment and debug would be very nasty. However that is matter of context. In bigger system it's more reasonable to buy more safety for price of simplicity, because I doubt any of competitors in the benchmark is as simple as C.
