[Bug libstdc++/38889] New: [C++0x] std::bind doesn't work

["bangerth at dealii dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I feel like I must be doing something incredibly stupid (and I'm sorry
if indeed I do) but this:
----------------------------
#include <functional>

void goo(int);
void foo() {
  std::bind (goo,1)();                      // works
  std::bind (goo,std::placeholders::_1)(1); // does not work
}
----------------------------
doesn't appear to work:

g/x> /home/bangerth/bin/x86/gcc-mainline/bin/c++ -std=c++0x -c x.cc

What do I miss?

Thanks in advance
