I also like:
-Wextra -Wformat=2 -Wformat-overflow=2 -Werror=format-security
to get more useful warnings, and error if there are security issues like totally
variable format strings; use `info gcc W...` for descriptions; YL/100kmMV
I have also found the following work well for development with recent gcc:
-fanalyzer -fsanitize-recover=all
-fstack-check -fstack-protector-all
--param=ssp-buffer-size=4
but may be inappropriate for production builds; use `info gcc f...` for
descriptions.
