Similar failures have been reported for java on IA-64.  It seems to be
reproducible on any target with -gdwarf-2.  Here's a short, unpreprocessed
example with the 3.0 prerelease:

[jsturm@mars jsturm]$ cat e.cc
#include <iostream>

using namespace std;

int main(void) {
	cout << "hello world" << endl;
}

[jsturm@mars jsturm]$ g++ -gdwarf-2 -g1 -c e.cc
