GitHub actions on Ubuntu 22.04 get stuck in a AddressSanitizer:DEADLYSIGNAL loop

Reported in various repos:

google/googletest#4491
quantumlib/Stim#717 (comment)
NOAA-OWP/ngen#767

I haven't seen a workaround except to disable these runners

I can't repro this on any of my machines with any of my build configurations

Ah workaround exists in actions/runner-images#9524

    - name: Fix kernel mmap rnd bits
      # Asan in llvm 14 provided in ubuntu 22.04 is incompatible with
      # high-entropy ASLR in much newer kernels that GitHub runners are
      # using leading to random crashes: https://reviews.llvm.org/D148280
      run: sudo sysctl vm.mmap_rnd_bits=28

Oh well, I guess a workaround is needed:
