No,

char * bob = 0*0;

will compile. Everything that evaluates to a zero at compile time will work. That's what I actually meant by saying "zero constant". The fact that it is possible to assign various constant expressions with the zero result to pointers looks like a misfeature, but it is minor at best.

On the other hand,

int i = 0;

char * bob = i;

will not compile, as 'i' does not qualify as something that evaluates to a zero at compile time.
