Use proper caution when opening attachments, clicking links, or responding. make rock-dbg_defconfig make savedefconfig cp defconfig arch/x86/config/rock-dbg_defconfig This also enables UBSAN, which can help catch some types of bugs at compile time.
Enabling UBSAN cause compiler insert code to perform certain kinds of check before operations that may cause undefined behaviour. I think it catches errors at run time, not compile time, and increases kernel size.
