[libdc1394-devel] Bug with out of order enqueue on os x

[Andrew W. <aw...@ui...>]

Hello-

I think I have found a bug in the mac specific code that prevents out  
of order enqueueing.  My code relies heavily on this feature, which  
lets me keep around old frames without copying them out of the ring  
buffer.  I have replicated the problem in a slightly modified  
helloworld.c, which I have included.  The problem exists in both rc5  
and rc7 on my PPC mac.  The problem does not seem to exist on linux  
with rc5.

If you set
#define ENQUEUE_OUT_OF_ORDER 0
the code keeps running happily.

If you set
#define ENQUEUE_OUT_OF_ORDER 1
the code gets stuck after a few frames. (Maybe when it gets back  
around to the first frame in the ring buffer that was enqueued out of  
order?)
