No, the issue did not reproduce with `ld`. Linking with `ld` and then running `strip` worked fine.

Even if the root cause is that `strip` does something wrong, I think `lld` needs to be compatible with that (or wait for `strip` to change). It does not seem reasonable for `lld` to emit binaries which break when stripped by the standard tool.

There is also the separate issue of crashing when linking rust code (https://crbug.com/325133695).
