 I get a SIGBUS when executing the following code:

 {{{
 #include <iostream>
 #include <boost/coroutine/coroutine.hpp>

 typedef boost::coroutines::coroutine<int()> generator;

 void foo(generator::caller_type& yield)
 {
   for (std::size_t i = 0; i < 10; ++i)
     yield(i);
 }

 int main()
 {
   boost::coroutines::attributes attr(false /*don't preserve FPU
 registers*/);
   generator gen(foo, attr);
   while (gen)
   {
     std::cout << gen.get() << std::endl;
     gen();
   }
   return 0;
 };
 }}}

 I tried with gcc 4.8 and clang 3.3 on Mac OS X 10.8 and with gcc 4.8 on
 Linux (CentOS 6). I also tried with the latest Boost trunk (r85977) on Mac
 OS X 10.8.
