The -Wformat-insufficient-args for clang is useful to detect the situation when the total number is unmatched between format specifiers and arguments. Originally, this option is enabled by default(Link[1]), but it is disabled by -Wno-format explicitly so that we can't detect this unmatched situation. We can enable it by adding this option after -Wno-format.
