I am trying to understand and debug the issue presented at [https://s3.amazonaws.com/julialang-reports/nanosoldier/pkgeval/by\_date/2024-12/10/Econometrics.primary.log](https://s3.amazonaws.com/julialang-reports/nanosoldier/pkgeval/by_date/2024-12/10/Econometrics.primary.log).
Is there a way to test the functionality that NanoSoldier is performing locally?

I presume this is just ["Instruction does not dominate all uses!" after IRCE pass · Issue #63984 · llvm/llvm-project · GitHub](https://github.com/llvm/llvm-project/issues/63984) and so not really something to worry about.
To reproduce locally I think you need to build Julia with `LLVM_ASSERTIONS=1` and then run the tests after starting Julia with bounds checking.
