Another test case (should I file another bug?):

blockquote
struct Class
{
Class() { }
/* implicit copy constructor */
void Method() const; // undefined
/* Class has no data members */
};

void f(); // undefined

void g( Class x ) // pass by value
{
f();// call undefined function
x.Method(); // call method on parameter
}

void h()
{
Class x;
g( x );
}
blockquote

$ g++ -Wuninitialized -O3 -c -o /dev/null file.cpp
file.cpp: In function 'void h()':
file.cpp:20: warning: 'anonymous' is used uninitialized in this function
$ g++ -dumpversion
4.4.0

BTW: I'm just now trying to build our stuff with GCC 4.4.0. I've run into two
warnings. The first is comment 0. The second may or may not be similar to the
above, except that it has data members -- but still no copy constructor or
assignment operator (no need). For fun, I've added them and am rebuilding now.
If that doesn't fix the problem, I'll probably be back later. :)
