We're working on that; see Jack's response and my follow-up.

Sorry, that was never supposed to work: it was a definite bug that 
you could do that and not get an error message.  The bug is now 
fixed.  The point is that we're supposed to able to do arbitrary C 
floating-point arithmetic with matrices, and you can't do that 
with NAs.  So matrices are not allowed to contain NA.  I'm pretty 
sure it's in the manual.

Perhaps I should ask: why do you want NAs in a matrix?  Maybe we 
can think of an alternative approach.
