Maybe this:

>Pizlix is LFS (Linux From Scratch) 12.2 with some added components, where userland is compiled with Fil-C. This means you get the most memory safe Linux-like OS currently available.

You need to annotate your program with indications of what variable tracks the size of the allocation. So, sure, but first work on the packages in the distro.

Note that corresponding checks for C++ library containers can be enabled without modifying the source. Google measured some very small overhead (< 0.5% IIRC) so they turned it on in production. But I'd expect an OS distro to be mostly C.

Get gentoo, add this to CFLAGS and start fixing everything that breaks. Become a hero.

It is called Solaris, and has this enabled since 2015 on SPARC.

>I want an OS distro where all C code is compiled this way.

You first have to modify "all C code". It's not just a set and forget compiler flag.

Fedora and its kernels are built with GCC's _FORTIFY_SOURCE and I've seen modules crash for out of bounds reads.

What are you hoping it will achieve?

does any distro uses clang? I thought all linux kernels were compiled using gcc.
