I reproduced the failure on my MBP13 with 'fastdebug' and 'slow debug' bits
with these options:

VM_OPTIONS=-Xcomp -XX:+CreateCoredumpOnCrash -ea -esa -XX:CompileThreshold=100 -XX:+UnlockExperimentalVMOptions -server -XX:-TieredCompilation -XX:+DeoptimizeALot

and then retested with the fix in place with 'fastdebug' bits and the failure
no longer reproduced.
