Consistent core dump of fio 3.36

Hi -

Running this command:

# fio --name=filecreate --directory=/data/fio-test \
   --nrfiles=100000 --filesize=4k --rw=write --bs=4k \
   --ioengine=sync --create_on_open=1 \
   --openfiles=128 --numjobs=8 --group_reporting

results in a consistent core dump:

Is there something wrong with my syntax?
