Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Priority|P3 |P2 Target Milestone|--- |7.2 --- 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).
