Yes, I fixed it in https://github.com/aya-rs/bpf-linker/commit/c36c254ae4db8d7bddd33752dd189334a4c58f83 and https://github.com/aya-rs/bpf-linker/commit/e474f8262db57f1344636466a644cc8929bd25ba.

The purpose of this proposed change is to save future users of the C API the same pain. I have added tests.
