We have one in vctrs but it's not exported:
https://github.com/r-lib/vctrs/blob/main/src/hash.c
The main use is vectorised hashing:
If you can afford a dependency on rlang, `rlang::zap_srcref()` deals
with this. It's recursive over expression vectors, calls (including
calls to `function` and their hidden srcref arg), and function
objects. It's implemented in C for efficiency as we found it to be a
bottleneck in some application

Do patches get filtered out?
Please find it there:

I'm also happy to post it on the bugzilla if that makes sense.

Hello,
We've run into this issue multiple times and it's often a head
scratcher when it happens. We are using workarounds but it would be
great to fix this for R 4.3. Would an R core member have time to
review the patch that we supplied in
https://bugs.r-project.org/show_bug.cgi?id=18489 ?

Hello,
I started using clangd to get better static analysis and code
refactoring tooling with the R sources (using eglot-mode in Emacs, it
just works once you've generated a `compile_commands.json` file with
`bear make all`). I noticed that the static analyser can't understand
several header files
