#include <string>

int main()
{
  std::string x;
  return 0;
}

fixed in g++-4.2

I confirm this too (just hit this bug). It has been reported however that the same GCC version (4.1.2) compiled from vanilla sources does work correctly with that snippet of code.

4.2 is now the default compiler for hardy
