This is actually quite an interesting topic in its own right, but not quite the discussion above, which is about whether C or Rust include a GC or is considered to "use" the GC you hand-rolled or pulled in from a library.

I wouldn't consider FilC's GC a GC in the conventional sense either, in that code compiled with Fil-C is still managed manually, with the (fully-fledged) GC effectively only serving as a way to do runtime validation and to turn what would otherwise be a UAF with undefined behavior into a well-defined and immediate panic. This aspect is in essence an alternative approach to what is done by AddressSanitizer.

I'll have to look a bit more into Fil-C though. Might be interesting to see how it compares to the usual sanitizers in practice.
