I don't expect C to be portable assembler. I expect it to be a simple fast language with clear rules. I am not sure what you mean by an idiom here. I suppose you mean assembler idiom as in C it was always a simple bug in logic. Obviously you can't just use idioms from one language in another without checking what the rules in the other language are.
Platform specific behavior should be as rare as possible. It's a recipe for bugs. The rule is simple enough and major compilers have flags to prevent the overflow. Obviously you pay the performance penalty for using them. It's a choice you're free to make as it should be.
