How do I reproduce the failure? I tried with alpine:edge docker image with --platform riscv64, but the test didn't fail.

I tried to reproduce on my end with podman and --arch riscv64 and I get a riscv64-section-order crashes consistantly with both master and v2.31.0. riscv64-shared-abs-sym didnt fail as well.

The alpine riscv64 runs on real hardware (scaleway and milkv pioneer),
