This is compiled with a MS C++ compiler with the ANSI C(++) (/Za) option
enabled.
It produces the compiler error shown in the source.
I wonder why ANSI C++ cannot accept a reference to a temporary object
(the return value from iFunc()) unless the reference argument is const?
After all, the temporary object is alive till the call to vFunc2 is
finished?
What is the danger of modifying the temporary object in vFunc2?
