--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
We do now have the analyzer and -Wuse-after-free.  I don't think a rust-like
borrow checking feature will ever work or is sensible to implement in C.  Use
rust if you need such a feature.

I'm also not sure a "weaker" form of borrow checking is actually useful.

That would leave "custom" alloc-free like attributes using the -Wuse-after-free
or the corresponding analyzer diagnostics without any other semantic
side-effects.  Is that what you actually want?

--- Comment #10 from uecker at gcc dot gnu.org ---

I would say it is rather likely that C will get something like this at some
point. 

BTW: Any use of the pointer value after free as in comment #2 is UB.
