Product: gcc

Source files
gcc version 7.2.0 (GCC)
system type: x86_64-pc-linux-gnu
command line to compile and run:
g++ -Wall -Wextra main.cpp && ./a.out
and
g++ -Wall -Wextra main2.cpp && ./a.out
for second version of program.
Binary from main.cpp, in which class is created by following way:
B* b = new B();
creates following output:
Constructor
0
Binary from main2.cpp, in which class is created by following way:
B* b = new B;
creates following output:
Constructor
0
Destructor
So destructor for B's constructor argument (A class) is not called when giving
'()' when creating B.
Clang in version 5.0.0 produces:
Constructor
0
Destructor
in both cases. Source files included
