The second should definitely _not_ be allowed. * definitely goes with the type in 
D (as it should have in C), not the variable. So, the *b = null makes no sense.

However, I'm vere suprised that the first one succeeds. I think that it should be 
reported as a bug. All variables declared on the same line are supposed to have 
the same type.
