I am running fio (HEAD:a28b019) on OS X (10.8.2) and just ran into a segfault after more than an hour of running the benchmark. Will dig into this more but wanted to check if someone else had run into this. I did manage to get a core though. There were three threads running with two sitting in __semwait_signal () (via usleep) and the third was: [Switching to thread 3 (core thread 2)] 0x000000010fcf7910 in thread_main (data=0x1105fe000) at backend.c:510 510 if (break_on_this_error(td, io_u->ddir, &ret)) (gdb) where #0 0x000000010fcf7910 in thread_main (data=0x1105fe000) at backend.c:510 #1 0x00007fff885d1742 in _pthread_start () #2 0x00007fff885be181 in thread_start () It seems like io_u is null here.
