I've added a simple example demonstrating stack unwinding.
It is interessting that stack unwinding works for this example
(and all others because stack unwinding is the default in 
boost.coroutine) using clang 3.2.
The unit test in directory test is aborted because an assertion is 
violated, e.g. postconditon
  (flag stack unwounded) in coroutine_object<>::unwind_stack_() failed.
In a gdb session I fgured out that
1.) jump_fcontext() is not invoked inside unwind_stack_()
2.) I see two stack_frames of ~coroutine_object() even if the destruct 
has a simple body

I think this is a strange issue of clang.

so long,
Oliver
