I also see a fair few elements on that list as being problematic, to say the least. Can't stand Rust, though, so for those times I really need high performance I try and keep my C knowledge sharp-ish.

Fortunately GCC has a whole bucket-list of warnings that can be enabled (I like compiling with -Wall -Wextra -pedantic, myself) which can, combined with proper tooling, catch many issues.
