9172	Crash when not preserving FPU	Alexandre Hamez <alexandre.hamez@…>	olli	"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."	Bugs	closed	To Be Determined	coroutine	Boost 1.54.0	Problem	invalid
