Steps To Reproduce Windows:
set OSDPROCESSORS=1
mame64 -window akatana

Linux:
OSDPROCESSORS=1 ./mame64 -window akatana
Additional Information On Windows it just exits back to the command-line without any message.

 The problem is with the queue allocation. In case there is only one processor osd_work_queue_alloc() won't allocate any threads for queues unless they are WORK_QUEUE_FLAG_IO.

 I hit this today on pinkswts when I was doing a benchmark run forcing -numprocessors 1.

'mame pinkswts -bench 90 -numprocessors 1 -norc'
