It is certainly possible since invalid values are getting used if the 
right conditions exist.  I know in my case, the values were int16, so I 
would not have experienced NaNs, but if the buffer was supposed to 
contain float data and reading outside the buffer happened I would 
expect NaNs to occur eventually.

Not saying that this is the cause of those, but it surely could be.
