multiprecision assign does not deal addequately with sign

[cerquide@…]

The following code provides the output:

0

-0

Looks like the positive sign is not set after assign is called.

#include <iostream>
#include <boost/multiprecision/cpp_int.hpp>

boost::multiprecision::int128_t x("0");

int main(int argc , char **argv) {
  std::cout << x << std::endl;
  x = -1;
  x.assign("0");
  std::cout << x << std::endl;
}

I'm unable to reproduce by either current Git develop or Boost-1.55, which compiler/platform is this?

Never mind, I've reproduced, testing fix now.
