Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |ASSIGNED Assignee|unassigned at gcc dot gnu.org |msebor at gcc dot gnu.org --- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> --- Simply avoiding -Wrestrict for null arguments would be a simple workaround for this case. Beyond that and your other suggestions in comment #4, improving jump threading would be worthwhile not just to avoid interactions with the sanitizers but in general. Let me put together a patch with the first change for now and see about the threader improvements in GCC 9.
