fio crash when using verify

[scameron@beardog.cce.hp.com]

Hi Jens,

I'm running into a crash with fio today, seems to be easily reproducible.

[root@msablackburn saperf]# fio --version
fio-2.1.11-2-g90811

(top of current git tree.)


[root@msablackburn saperf]# fio ./2drive_sdr_verify.fio
4_KiB_RR_drive_r: (g=0): rw=randwrite, bs=4K-4K/4K-4K/4K-4K, ioengine=libaio, iodepth=170
4_KiB_RR_drive_s: (g=0): rw=randwrite, bs=4K-4K/4K-4K/4K-4K, ioengine=libaio, iodepth=170

fio: io_u.c:1315: __get_io_u: Assertion `io_u->flags & IO_U_F_FREE' failed.a 58m:59s]

my fio job file looks like this:

[root@msablackburn saperf]# cat 2drive_sdr_verify.fio
