rtd520 broken in 0.7.65

As of version 0.7.65 (and CVS), I'm getting "buffer overfow" errors on 
fast sampling.  If I drop back to 0.7.64, then it runs fine.

Above about 50K sample/second, it consistantly fails at exactly 40960 
samples (with a 64K buffer).  If the input buffer is 32K, then it 
happens at 24576 samples.  At 128K, it happens at 73728 samples.

With the 0.7.64 release, I can do 560K sample/sec without any problems.  
CPU load isn't a problem in either case.  The program is just reading 
and discarding the data.

The diffs in rtd520.c between those versions are trivial (spelling 
fixes).

Anybody have an idea what's broken?
