This is an open issue upstream reported in 2023 by another distro https://github.com/technion/libscrypt/issues/60 It fails when file crypto_scrypt-nosse.c is compiled with clang 15 -O2 or gcc 13.2.1 -O3. With optimization to -Os/-O2, or with clang 14 or an earlier gcc and keeping -O3, it passes. I verified that it still fails the same with gcc 14.2.1 -O3 and passes with -O2.

Rereading the upstream, I got the clang optimization backward. They say it passes with clang -O2 and fails with -Os. Also passes with gcc 10.5.0 but fails with gcc 12.3.1.
I'm reducing it.
