New description:

 After upgrading to MacOS 10.14 Mojave from 10.13 High Sierra and migrating
 Macports, I could not build `mythtv-core.26` which I'd been maintaining
 locally after being marked obsolete in the Macports tree. When building
 `mythtv-core.28`, I see

 {{{
 :info:build tv_play.cpp:216:34: error: reference member 'm_menu' binds to
 a temporary object whose lifetime would be shorter than the lifetime of
 the constructed object
 :info:build     MenuNodeTuple(void) : m_menu(MenuBase()) {}
 :info:build                                  ^~~~~~~~~~
 :info:build tv_play.cpp:217:21: note: reference member declared here
 :info:build     const MenuBase &m_menu;
 :info:build                     ^
 }}}

 Full log attached.
