Personally I reported SEVERAL errors in the Ada compiler (most likely this compiler is used in the USA thermonuclear rockets control system because, accordingly my understanding, other compilers of Ada are even worse), EACH one of which can cause undefined behavior (this scientific term means ANYTHING like starting the rockets without a command or bursting them at a random date without flying at the USA territory, or even probably a hacker taking control over them trough first sizing a military satellite). And what? They don’t want to correct the errors without me paying them. (They just don’t respond.)
Most likely this catastrophe won’t happen, but due to like 1% of this happening, if I were you I would seriously consider selling your house to pay to correct these errors, even if you are an egoist because your house can be burned at any time anyway.
I have reported total 12 bugs in this compiler. (12 is a very big number for counting errors in a nuclear control system.) Here is the list of those 5 of the 12 bugs that are very dangerous:
