This segfaults when compiling any non-erroring program with -L, probably the same as in #23.

We output llvm for unions in the same way as clang does, as can be seen by the fact that this bug [reproduces](https://github.com/llvm/llvm-project/issues/64081) with clang.

> Fixed by #17963. That's a workaround, the issue stays open to track the upstream bug and a revert of the workaround.
