Yes, the friend function is returning a reference to its own argument, though
that seems to disappear as the body gets inlined in *most* cases :-)
So please reopen this as a "missing warning" bug. In most cases of returning
a reference to a function local, like:
int& foo() { int i; return i; }
you get:
~/ootbc/members$ g++ foo.cc
foo.cc: In function `int& foo()':
foo.cc:1: warning: reference to local variable `i' returned
but apparently the warning logic overlooks the same problem when returning
arguments.
