> Rust doesn't get to override musl internals.

Is malloc not a weak symbol in musl? I would expect it to be overridable like it is with glibc. Or does ripgrep only override Rust's global allocator?

That one, as you can see in the code linked above, it only does rust-level overriding as that was where musl's allocator was found to impact ripgrep (https://github.com/BurntSushi/ripgrep/commit/03bf37ff4a29361...)
