In the benchmark run preflight checks,

$ numactl --membind=0 --cpunodebind=0 ./jdk-17/bin/java -Xms150g -Xmx150g -Xmn140g -XX:-PrintWarnings -XX:+UseLargePages -XX:+UseNUMA -XX:-UsePerfData -XX:+UseG1GC -XX:+AlwaysPreTouch -XX:ParallelGCThreads=32 -version

Charlie had a good idea to try -XX:ParallelGCThreads=1 but it crashes the same way.

I can repro this on x64 and ARM systems with 17-b32.
