How about we enable it by default for build with new enough GCC (so that it reports these errors without silently dropping the non-NULL checks)?Yes, it seems that we can use -fno-delete-null-pointer-checks to prevent GCC from optimizing away the NULL pointer checks, while having nonnull attributes enabled all the time.
Or that, yes. So I'll drop this one.
