The derefencing is not the bug, it is at best one of its symptoms.

In D (in constrast to C++) the null ptr dereference is 
implementation defined.[1] I.e. if you need a test program that 
dereferences a null ptr you can write one in D (you cannot in 
C++). If that program does what it is expected ("[The] program 
will be aborted" [1]) one can hardly say that such a program 
contains a bug.
