Compiler bug? Linker bug? Windows Kernel bug
I used to be surprised when people came across these bugs. I would think: a kernel bug! They must have truly hit an edge case for something like that to skip into production. But then I read Showstopper: The Race to Build Windows NT, specifically the part where that OS shipped with 65,000 known defect (and it was considered one of the most stable software releases of all time), and it became clear to me that these bugs are probably known by the team when the OS ships but just not considered high priority enough to fix. Same with the recent articles about iOS and engineers not getting time to fix P2 bugs. Long story short my entire perspective on kernel bugs (and partly software development) changed and I began to think of them more as known flaws that weren’t fixed because of schedules rather than unknown bugs that were uncovered in the wild.
