--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> ---
So it would be interesting to see if it faults when placing the strings at the
edge of a page boundary...
In any case reading excess bytes from an aligned location is ok but of course
unfortunate for tolls like valgrind. So not sure if a bug (but see above).
