+Subject: [PATCH] Add correct offset for end of chunk
+
+Using `&current->chunk_ + x` will add `x * sizeof(current->chunk_)` to
+the pointer, but we only want to add `x`.
+
+Adding a much larger number still "works" on 64bit systems (although it
+does not perform the intended check). However on 32bit platforms this
+wraps (at least in the way used by sllisttest.cc) and the "end" of the
+chunk is suddenly before the beginning.
+
+Closes #57
