fio signal 11

Hi All,
Using the latest version from git, I am getting a signal 11 error when running some workloads.  It may be that workloads fail when we wrap around the device capacity (e.g. runtime and time_based).  See below example parameters:

# fio --name=test_job --ioengine=libaio --direct=1 --rw=write --iodepth=32 --size=100% --numjobs=1 --bs=1m --filename=/dev/nvme0n1 --group_reporting --write_bw_log=test_job --write_iops_log=test_job --write_lat_log=test_job --log_avg_msec=1000 --disable_lat=0 --disable_clat=0 --disable_slat=0 --runtime=1500s --time_based --ramp_time=5s --output=test_job

fio-2.11-17-ga275
Starting 1 process
fio: pid=145763, got signal=11

In fio-2.11 (release), the error did not occur.

Regards,
Jeff
