 ### Bug Fixes
-
+- backend code: some getters crashed with `SIGSEGV`, see
+  [issue #19](https://github.com/wfjm/w11/issues/19). The culprit was the
+  automatic return type determination for the getter lambdas. Changed back
+  to using bind, now `std::bind`, for method forwarders. This is safer and
+  also more compact.
