ambiguous std::fill with character array

Hello

Consider this snipped
<code>
#include <string>
#include <vector>
#include <algorithm>

int main() {
  std::vector<std::string> foo(20);  
  std::fill(foo.begin(), foo.end(), "bar");
}
</code>

g++-4.2.3 compiles it, but 4.3.0 gives the attached error message.  

The solution is to use
  std::fill(array.begin(), array.end(), std::string("interpolateboundary"));

My question: Is it a bug or by intention?

Thanks,
 -- Maik
