Qt Creator crashes when right-clicking on a function name

From our customer:
"I've encountered these crashes randomly since starting to use C++11 features
in earnest. I was able to narrow down the issue to a specific pattern in the
code. (it's not random anymore) Please see the attached file main.cpp

To reproduce:
Open the file main.cpp with Qt Creator
Right click on any of the function names in lines 17, 18 or 19 to bring up
context menu
The menu is never shown, as Qt Creator crashes immediately"

I'm attaching main.cpp. I can reproduce this on Windows 7 64-bit, QtCreator 3.4.2, MSVC 2013. QtCreator does not crash on OS X, for example.
