--- Comment #1 from Drea Pinski <pinskia at gcc dot gnu.org> ---
In GCC 16:
inv_expr 2: p_11 + ~(sizetype) ((n_16(D) - i_9(D)) + 4294967295)
on the trunk:
inv_expr 2: p_11 + ((sizetype) i_9(D) - (sizetype) n_16(D))
That seems wrong. n and i here are 32bit while sizetype is 64bit.
This is why `(char *)0x10000ffffffff` fails.
