Yeah, the full ref run takes quite a long time on my banana pi f3 so I've just been using train for now :)

There isn't a stack trace because those failures are internal errors detected by the benchmark itself. I'm not sure how exactly it works under the hood in SPEC. 

But for what its worth, 502.gcc_r and 525.x264_r are already failing with EVL tail folding on main today. Did the other benchmarks pass?
