// try this simpler code.

#include <stdexcept>
#include <ext/concurrence.h>

namespace

  unsigned int i;

void* add(void*)
{

  {
    ++i; // break here
  }
  return 0;
}

check_thread_create(int ret)
{
  if (ret != 0)
    {
      char buf[10];
      sprintf(buf, "%u", ret);

      std::string error("pthread_create failed: ");
      error += buf;
      error += strerror(ret);
      throw std::runtime_error(error);
    }

int main()
