A bug with variables and functions of the same name?

[darby johnston <darbyjohnston@xxxxxxxxx>]

Hi,

Found something sort of odd:

int a(int);

int main(int, char **)
{
  int a = a(100);
  return 0;
}

> g++ -Wall -o foo foo.cxx
foo.cxx: In function ?int main(int, char**)?:
foo.cxx:7: error: ?a? cannot be used as a function

That seems normal, but add a "const" to the above:

  const int a = a(100);

And it compiles without any errors (and even links
ok). I made this simple test case from a bug I found
in my code, which even stranger, emitted warnings
like:

warning: ?retval.170? is used uninitialized in this
function

Of course, I don't have any variables named
"retval.170". Is this a bug with gcc?

gcc version 4.0.3 (Ubuntu 4.0.3-1ubuntu5)

Thanks for any help!
