This would at least not be defective.

Note: this is a gcc-specific/proprietary library-internal implementation
detail, user-code must not use.

That said, __SIZEOF_POINTER__ would provide a way to prevent the side-effects
of this junk to hit the users.

This still doesn't mean this code should be kept - If this was a programming
course, I would let you "fail the examination" because of this design.
