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/[email protected]/ 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.
