macOS linker_messages `__eh_frame section too large`; false positive?

What happened

After upgrading to 1.97 on macOS, I'm now getting this linker_messages warning:

warning: linker stderr: ld: __eh_frame section too large (max 16MB) to encode dwarf unwind offsets in compact unwind table, performance of exception handling might be affected
  |
  = note: `#[warn(linker_messages)]` on by default

warning: `crates_io` (bin "background-worker") generated 1 warning

I have no idea what this means or if I'm supposed to do anything about this. I read the release blog post that said some of these are false positives that should be filtered out, so I'm thinking this might be one of those?

How to reproduce

I get this consistently when building the background-worker bin of crates.io.

$ git clone https://github.com/rust-lang/crates.io.git
$ cd crates.io
$ cargo build --bin background-worker

System information

I'm on an Apple M1 Max using Sequoia 15.7.7.

$ rustc --version --verbose
rustc 1.97.0 (2d8144b78 2026-07-07)

Reproduce the warning with cargo build --bin background-worker in crates.io on macOS using rustc 1.97.0, then trace how linker_messages handles this linker stderr output. Determine whether the __eh_frame warning is a false positive that should be filtered; done means the warning is correctly classified or the behavior is clearly addressed.
