#### Local build testing
- I built this PR locally for my native architecture, (ARCH-LIBC)
  -  x86_64-glibc
- I built this PR locally for these architectures (if supported. mark crossbuilds):
  - aarch64-musl (crossbuilt on x86_64-glibc)
    - It has the same bug as described in #45166 in both this version and the current version in repo (2.0.0_2)
    - (I'd fix it myself if I knew how to)
    - otherwise works well
