I love hitting these things in the real world. Not the big, but the comment. You just know someone spent a fortune in time and company resources to never solve the problem and their frustration level was ragequit. But then something stupid like adding

while (0){};

Suddenly made it work and they were like, fuckit.

Usually it's a bug somewhere in a compiler trying to over optimize or something and putting the line in there caused the optimization not to happen or something. Black magic.

The downside is that the compiler bug probably gets fixed, and then decades later the comment and line are still there...

I used to work on an old DOS product and we didn’t have a debugger so we used to have a DEBUG command line argument with

if (DEBUG) printf(“debugging”);

to try to see what was happening and the number of times that code alone fixed the problem was scary.

I mean . . . I still do this on my own stuff. If I'm interested in optimizing for speed I'll do it as #ifdef instead of if ()
