Some notable observation about the problems observed: Some notable observations about the problems observed:
Verthash is a mystery, it only produces rejects on ARM even with no targtetted code, only compiled C. The same C source works on x86_64 but not on AArch64. Tried with -O3 & -O2. In all other cases falling back to C was always successful. Verthash data file creation and verification work.
