The gcc bug list/group is not the right place to report your problem.
Please use g++-bug for future problems with the C++ compiler.

No, there is no bug.

This is correct behavior.

As it should be.

That is correct beahvior.

> The program works fine with an old release of g++ (g++ 1.37.1).

That is true, but does not matter.  It is a desupported feature if you
will.  Please read a recent ANSI draft or the ARM.  The short of it
is, the commented out line IS necessary.
