Assertion on "type that is unsized" and crash

[Erhannis]

Ubuntu 22.04.5 Jammy
I'm trying to convert this cpp library to c: https://github.com/vinniefalco/DSPFilters , specifically ./shared/DSPFilters . I cloned https://github.com/llvm/llvm-project (llvmorg-19.1.1 / d401987fe349a87c53fe25829215b080b70c0c1a), built it (I think according to your instructions, rather than the llvm ones - it did build though), cloned llvm-cbe into the llvm/projects folder and built it as instructed. All fine and good. I also built the whole llvm-project directory, because it seemed like I needed llvm-link, but I'm not sure if that ended up being true. I've cloned DSPFilters (master / acc49170e79a94fcb9c04b8a2116e9f8dffd1c7d), cd shared/DSPFilters/source, and do the following:

Some of the files do work, like Custom.ll, but it seems like most of them fail in this way.

I tried merging them into one .ll first, but that didn't help:
