Well, as long as these darn modern operating systems let you use
memory that isn't even there and then just kill the process instead of
signaling an error, there's no chance that the runtime can raise
Storage_Error.
Same with malloc(). Chances are much higher you just get killed than
this one ever returns NULL that you can handle. And everyone still
keeps telling you, you should check the return value. ;-(
