Description Behrooze Sirang 2023-12-20 00:37:14 UTC 
I appear to be hitting an internal assertion in the gold linker causing linking to fail. It is 100% reproducible for a particular build target. A slight change in the source code can get rid of the issue, which I assume is by chance the problematic assembly sequence is not generated.

I was able to reproduce this on binutils 2.41 as well as on 2.34

I can work around this by downgrading the optimization level to `-O1`. I also found that I can work around this by disabling the errata fix via `--no-fix-cortex-a53-843419` option. However, I do not want to disable it given that it is meant to work around a hardware erratum.

If needed, I can provide more information about my build environment.
