It does however recognize the standard strncpy() and optimizes away the extra checks for that, using only 1688 bytes in the end. I have another larger patch that we could use in addition to this one, in order to shrink the stack for -fsanitize-address-use-after-scope (with gcc-7.1.1) as well, but that would not be appropriate for stable backports, so let's focus on this one first.
