Hi Jonas, that interesting results! I don't have the time right now to dig into the details, but..

In D133452#3877904 <https://reviews.llvm.org/D133452#3877904>, @Hahnfeld wrote:

There was a discussion on Discord these days about it: https://discord.com/channels/636084430946959380/687692371038830597/1033427215448293396
The error originates from JITLink's `DebugObjectManagerPlugin` and it should be fixed with: https://github.com/llvm/llvm-project/commit/b26f45e5a49ae363164e7dbbf57eadd9e78d612c
Does it work for you? Otherwise, can you disable the plugin temporarily and try again?

Just a guess: Maybe the `EHFrame` plugin adds the extra dependency here. Do you need exception handling and/or backtraces? Maybe check and disable the plugin temporarily as well?
