+    ln: with -sr, don't segfault for a TARGET of ''
+    
+    Prior to this change, "ln -sr '' F" would segfault, attempting
+    to read path2[1] in relpath.c's path_common_prefix function.
+    This problem arises whenever canonicalize_filename_mode returns
+    NULL.
+    * src/ln.c (convert_abs_rel): Call relpath only when
+    both canonicalize_filename_mode calls return non-NULL.
+    * tests/ln/relative.sh: Add a test to trigger this failure.
+    Reported by Erik Bernstein in 739752@bugs.debian.org.
+    Fixes http://bugs.gnu.org/17010.
