Oh, bummer. (It worked on Fedora 39 though!)
I do object:
I think the interim fix should instead be to add Linux to the list of
platforms for which we use the "rust-internal-llvm" option by default.
This is the workaround I have been using. Mixing pkgsrc llvm with
rust's bundled libunwind seems less safe to me and we can treat Linux
the same as SunOS and Darwin.
