arc profiling broken on gcc-3.0.4 Linux

[Neal D. Becker]

It looks like all arc profiling is broken on gcc-3.0.4 Linux.  Here's
what happens:

#include <iostream>
#include <stdexcept>

using std::cout;

main() {
  cout << "hello world\n";
}

g++3 -v -o Hello Hello.cc -Wall -O6 -ffast-math -fprofile-arcs -malign-functions=4 -fstrict-aliasing -g
