building 30_threads/condition_variable_any/cons/1.cc with the 4.4 branch

g++ -fstack-protector -std=c++0x any.cc -o any

and running the binary on a system with the shared libstdc++.so installed from
the 4.5 branch aborts.

#include <condition_variable>
#include <system_error>

int main()
{
  bool test __attribute__((unused)) = true;

  try 
    {
      std::condition_variable_any c1;
    }
  catch (const std::system_error& e)
    {
      perror("system_error");
      exit(1);
    }
  catch (...)
    {
      perror("system_error");
      exit(2);
    }

  return 0;
}
