LLVM build error on Alpine Linux x86

[orhun]

Describe the bug I'm the maintainer of heh for Alpine Linux, and hit a very weird build issue while building 0.5.0:

   Compiling heh v0.5.0 (/builds/orhun/aports/testing/heh/src/heh-0.5.0)
LLVM ERROR: Cannot emit physreg copy instruction
error: could not compile `heh` (bin "heh")

P.S. never seen such an error in my life 😳

To Reproduce The issue is reproducible on Alpine Linux x86, see the logs here: https://gitlab.alpinelinux.org/orhun/aports/-/jobs/1337171
