bug description:
-----------------
We compiled the attached source code using the command:
> g++ --save-temps build_and_destroy.cc -o bug
Running ./bug produced the following output:
A
A copy
A
~A
A.m:1
~A
~A
As you can see, returning the object in the function F didn't call the copy
constructor. We expect the following output:
A
A copy
A
A copy
~A
~A
A.m:2
~A
~A
