Of course it can, but my claim was there’s never a reason.  A pointer to 
uninitialized (or zero-initialized) memory that won’t be written is 
valid but not _useful_.  The reason you’d align a pointer is so you can 
store something there that needs to be aligned.  It’s not an accident 
that all of the current callers work that way.
