Depth Buffer Corrupt on Mac

[Taylor Veltrop]

The problem seems to be here: 3253922 WARNING Read: Depth buffer
is corrupt. Size is 0 (!= 614400)

The full log plus the configuration file follows. Any idea how to
proceed?

Ok, got this working now.

It turned out to be a pthread problem.  In Linux, sending an empty but initialized pthread_attr to pthread_create() was fine.  But on Mac I had to set that to NULL.  I thought the thread creation was failing because of a kinect init failure, but it turns out that the failed thread creation was causing a producer/consumer problem on the kinect.
