A few others I use are -Wsign-compare and -Wformat-nonliteral. Sign compare warns on possible bugs/vulnerabilities due to comparing signed and unsigned values.

A few others I use are -Wsign-compare and -Wformat-nonliteral. Sign compare warns on possible bugs/vulnerabilities due to comparing signed and unsigned values. Using nonliteral formats can lead to vulnerabilities (such as the famous attacks on FTP servers http://seclists.org/bugtraq/1999/Sep/328 http://seclists.org/bugtraq/1999/Sep/328)

-Wall includes -Wsign-compare
