GCC 14 is still in development, but it has a wonderful new feature in its static analyzer (-fanalyzer).
It can now draw beautiful Unicode diagrams showing exactly how you went out-of-bounds.
See https://inbox.sourceware.org/gcc-patches/20230531180630.3127108-1-dmalcolm@redhat.com/ too.
Thank you to the wonderful David Malcolm for implementing this - who also does a tonne of work with mentoring for GCC's GSoC programme, and working on docs to help new people get into GCC: https://gcc-newbies-guide.readthedocs.io/en/latest/index.html.

For all the people who still held any illusions that they are good at writing C:
"Look, human. This is where your weird human brain decided to introduce a fence-post error again.
Here, I have drawn you a picture. Sorry, crayons were out."

@thesamesam @gnutools I won’t pretend to really understand this, but I just have to say:
IT LOOKS SO COOL. Plus, visualizing things can greatly help folks who process better visually, so I’m a huge fan!

I should also say that if you want a distribution that makes it very easy to have multiple GCCs installed at once and is recognised for its high-quality toolchain maintenance, you know where we are 😉
