Manuel López-Ibáñez <manu at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |NEW CC|manu at gcc dot gnu.org | Known to work| |4.8.2, 5.0 --- Comment #11 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- I don't have GCC 4.9.1 to try, but I would assume it is confirmed according to Jack. If it did not trigger in 4.8, then it is technically a regression. __builtin_posix_memalign was introduced in r207595.
