Compilation problem when upgrading from g++ 3.3 to g++ 3.4

[Alex Vinokur]

Hi,

The code below has no problem with GNU g++ 3.3,
but it has a problem with GNU g++ 3.4.

Any suggestions?

------ foo.cpp ------
#include <vector>
using namespace std;

typedef char foo_t[3];
#define ELEM1 "ab"
#define ELEM2 "cd"

const foo_t a[] = {ELEM1, ELEM2};
const vector<foo_t> v = vector<foo_t>(a, a + sizeof (a)/sizeof (*a));

int main()
{
  return 0;
}
---------------------
