Yes, see your log:

but then:

+ patch
Hmm...  Looks like a unified diff to me...
The text leading up to this was:
--------------------------

Patching file contrib/libc++/include/type_traits using Plan A...
Reversed (or previously applied) patch detected!  Assume -R? [y]
Hunk #1 succeeded at 842.
Hunk #2 succeeded at 877.
Hmm...  Ignoring the trailing garbage.
done

E.g., it undoes the change to type_traits that was merged in the subversion update.
