Unreachable code detected

Well, you wouldn't want it to fall through, would you?
Well, on a X86, you'd need at 3 bit errors on the instruction to convert a RET (0xC2) to a NOP (0x90), but hey, I'm all for defensive programming! Marc

So, I just compiled a small web service that I, of course, did not write. Got almost 100 "Unreachable code detected" errors. Why? Here's an example:
case [some case]:
return CallSomeFunction(xmldata);
break;:rolleyes: Marc

wouldn't those be warnings? are is "warnings as errors" turned on?
If your actions inspire others to dream more, learn more, do more and become more, you are a leader.-John Q. Adams
You must accept one of two basic premises: Either we are alone in the universe, or we are not alone in the universe. And either way, the implications are staggering.-Wernher von Braun
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.-Albert Einstein -

They are warnings. I hate warnings. Warnings should be fixed, even if their not treated as errors by the IDE. Marc

When I started programming, structured programming was all the rage, and one of its fundamental principles was "single entry, single exit" for every block of code. While structured programming in no longer a primary development paradigm, it's principles are still valid. Putting a

Amen to that, I use code analysis tools to and eliminate all the issues those detect. Occassionally I have to use a pragma/code comment when I really intentionally did something, but its rare, and worth it for the number of bugs I detect early.

delete this;I fundamentally disagree, but it does depend on the language. In C++ and many other languages I use RAII instead to ensure nothing is ever missed.
