I have to work with folks who confuse size_t with int, and as a result they have overflow bugs depending on whether O_LARGEFILE is in use. So yes, I care. Not because printf format strings are terribly important, but because understanding and adhering to the type system is essential to write bug-free software.
- 0x12 15y agoIf they get overflow errors then your build process does not have the right warnings enabled/logged. Suggestion: enable -Wall and treat warnings as errors.
- pwaring 15y agoHandily, gcc has -Werror, which turns all warnings into errors. So -Wall -Wextra -Werror should catch most things.
- dodedo 15y agoOf course. You and I know they're doing it wrong, however sirclueless suggested above that type correctness is "arcane" and asks if "we would really care" when it comes to type issues in printf format strings.
