+Subject: [PATCH] Fix potential signed overflow in pointer arithmatic
+
+Pointer arithmatic results in implementation defined signed integer
+type, so that 's - src' in strlcpy and others may trigger signed overflow.
+In case of compilation by gcc or clang with -ftrapv option, the overflow
+would lead to program abort.
+
+Upstream-status: Submitted [http://bugzilla.mindrot.org/show_bug.cgi?id=2608]
