Unable to link use of hypr_util with -Zsanitizer=address on msvc

[russelltg]

I tried this code:

// Cargo.toml
// [package]
// name = "conflicting_weak_bug"
// version = "0.1.0"
// edition = "2021"

// [dependencies]
// hyper-util = { version = "0.1.3", features = ["client-legacy"] }

fn main() {
    hyper_util::client::legacy::connect::Connected::new();
}

With RUSTFLAGS=-Zsanitizer=address, I run cargo +nightly build --target=x86_64-pc-windows-msvc

I expected to see this happen: build succeeds

Instead, this happened: Build fails:

note: libtokio-b91778b05568f23f.rlib(tokio-b91778b05568f23f.tokio.1a77ed8b4a2c54db-cgu.0.rcgu.o) : fatal error LNK1227: conflicting weak extern definition for '__odr_asan_gen___rust_panic_type_info'.

Seems somwhat similar to #85461, however setting -Ccodegen-units=1 does not workaround the issue.
