Debug file of sled

I am currently experiencing an issue with the elfutils eu-addr2line tool. When
using it with a program written in Rust, I am unable to correctly retrieve the
filename and line number, which is possible when using the addr2line tool
instead.

Here is an example of what I am experiencing:

When using addr2line:
```
$ addr2line -V
GNU addr2line version 2.35.2-37.el9

$ addr2line -f -i -e sled-cache.debug 477be | c++filt -i
std::os::unix::fs::FileExt::write_all_at
/builddir/build/BUILD/rustc-1.66.1-src/library/std/src/os/unix/fs.rs:197
sled::pagecache::parallel_io_unix::pwrite_all
/home/agentzh/.cargo/registry/src/mirrors.ustc.edu.cn-61ef6e0cd06fb9b8/sled-0.34.7/src/pagecache/parallel_io_unix.rs:42
```

When using eu-addr2line:
```
$ eu-addr2line -V
eu-addr2line (elfutils) 0.188

$ eu-addr2line -f -i -e sled-cache.debug 477be | c++filt -i
sled::pagecache::parallel_io_unix::pwrite_all
/builddir/build/BUILD/rustc-1.66.1-src/library/std/src/os/unix/fs.rs:197:13
```

As you can see, the eu-addr2line tool does not provide the correct filename and
line number as the addr2line does. I would greatly appreciate any assistance or
advice on how to resolve this.

Thank you for your time and I hope to hear from you soon.
