mac osx上的boost asio示例崩溃

但它崩溃了:

From the console:
/Developer/SDKs/MacOSX10.5.sdk/usr/include/c++/4.0.0/debug/safe_iterator.h:127:
   error: attempt to copy-construct an iterator from a singular iterator.

Objects involved in the operation:
iterator "this" @ 0x0x100420 {
type = N11__gnu_debug14_Safe_iteratorIN10__gnu_norm14_List_iteratorISt4pairIiPN5boost4asio6detail16reactor_op_queueIiE7op_baseEEEEN15__gnu_debug_def4listISB_SaISB_EEEEE
(mutable iterator);
 state = singular;
}
iterator "other" @ 0x0xbfffee64 {
type = N11__gnu_debug14_Safe_iteratorIN10__gnu_norm14_List_iteratorISt4pairIiPN5boost4asio6detail16reactor_op_queueIiE7op_baseEEEEN15__gnu_debug_def4listISB_SaISB_EEEEE
(mutable iterator);
 state = singular;
}
Program received signal:  “SIGABRT”.
