Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Priority|P3 |P1 --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Seems starting with that revision we hoist *d before the loop (which would be ok only if it is guarded by if (b), as if b is false, it is completely valid that d is NULL or uninitialized etc. and causes trap). Richard, can you please have a look?
