Subject: Re:  GCC Compiles C++ program containing value-returning
 functions that don't return a value

The reference I'm reading ("The C++ Programming Language, 3rd ed.", pp.
148) says in section 7.3, "A value must be returned from a function that
is not declared void
...
int f1() { }                    // error: no value returned"

    So, according to a well-respected reference written by the author of
the C++ language, that statement, if I'm interpreting the meaning of
Stroustrup's comment correctly, should not be compiled by a C++
compiler. If that is true, then it should be caught by the compiler as
an error rather than a (optional) warning. But according to what you're
saying, it should only be undefined (and dangerous) behavior.

    Whenever you get a chance, could you let me know where you are
getting your information from? I'd like to take a look at it myself so
we can both be on the same page.

    Thanks in advance.
