It seems like you are encountering a specific compiler error related to the LLVM backend when using zksolc version 1.5.4. This error might be due to an issue with the LLVM version or a conflict within the library symbols used by your project.

Here are a few steps you can try to resolve this issue:

1. Update zksolc: Ensure that you are using the latest version of zksolc. Sometimes, updating to the latest version can resolve compatibility issues with LLVM.

2. Check for Duplicate Symbols: Review your project's dependencies to ensure there are no duplicate symbols or conflicting libraries being linked.

3. Rebuild LLVM: If possible, try rebuilding LLVM or using a different version that might not have this issue.

4. Consult the Community: Since this seems to be a more complex issue, I recommend discussing it further on the ZKsync developers discussions on Github. This platform can provide more tailored advice from developers who might have faced similar issues.

If the problem persists, sharing more details about your build environment and configurations on the Github discussions might help in diagnosing the issue more effectively.

Your feedback helps us serve you better. If this fully addresses your question, please give it a thumbs up. If it doesn't, please give it a thumbs down. This will inform the community and team so we can improve our support.

I was able to reproduce this, while the error message says to open a bug report with llvm, I've opened a new issue here:
matter-labs/era-compiler-solidity#188

I'm pretty sure these have been compiled successfully at least once, but I assume they forked or used an older version.

But for reference here was my full trace.
