fio 1.22 segfaults when pressing ctrl-c

[Erwan Velu <erwan@seanodes.com>]

I'm running fio with the surface scan example, and it just segfault and 
generate a core if I'm pressing CTRL-C during the test.

[root@max5 examples]# fio surface-scan
write-phase: (g=0): rw=write, bs=64K-64K/64K-64K, ioengine=sync, iodepth=1
verify-phase: (g=1): rw=read, bs=64K-64K/64K-64K, ioengine=sync, iodepth=1

**** I'm pressing CTRL-C ****
fio: terminating on signal 2
Quit (core dumped)
[root@max5 examples]#


Then same from gdb:

[root@max5 examples]# gdb --args fio surface-scan
