All warnings are uninteresting until they're not.

This warning (with a different function) actually saved my bacon once, pointing me to a very obscure bug in the code.

My practice is to use -Wall and make sure that the code compiles without any warnings at all. Then I don't have a deluge of warnings to wade through.

Remember -Wall isn't all. -Wall -Wextra is the new -Wall.

I recommend asan too, where possible.

Oh, you're right. I need to update my build system.

Why do compilers do stupid things like this? Seriously don't get why -Wall isn't all warnings.
