Sorry about the delay. Can you still repro this? What makes you think it's related to mprotect? If you can repro this, try following the emergency debugger instructions. Signal 4...
Can you try making the change yourself to `compute_cpu_microarch` in `PerfCounters_x86.h`? These are Zen5. I don't know what the CPU types are.
