Actually, you could probably not use *all* of the 64k. You have to
consider the reset vector, ram initialization data and global
constructor / destructor code that resides in the lower page, IIRC. 

>Is this a bug and will it be corrected in future releases ?
Probably, I'll have a look when I find time. Actually, such kind of
check should be done, IMO, by the linker and not the compiler.
