--- Comment #1 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Confirmed.

C allows to convert a pointer to data to any other pointer to data (possibly
modulo alignment restrictions).  What is *not* valid is accessing anything via
a type not compatible with its effective type (or via a character type).

So the restriction in rs6000_invalid_conversion errors for valid C programs.
What was it intended to accomplish?
