--- Comment #2 from Sergey V. Lobanov <sergey at lobanov dot in> ---
Looks like, it's not a bug. It is requires to set -mtune that forces
slow_unaligned_access=false, e.g. -mtune=thead-c90, e.g.
"riscv64-alpine-linux-musl-gcc-15.2.0 -O3 -mno-scalar-strict-align
-mtune=thead-c906 -U_FORTIFY_SOURCE -fno-stack-protector 2.c"
Unfortunately, spacemit vendor doesn't upstream their GCC pathces and doesn't
publish their GCC source code so I have to use their proprietary GCC cross
toolchain
