升压asio示例在mac osx上崩溃

Question

我想从MacOSX 10.5上的Boost asio示例运行blocking_udp_echo_server.cpp。

但它崩溃：

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”. 

从回溯：

任何人有任何想法？

Answer 1

据我了解，唯一保证的操作在singluar值是分配一个非奇怪的。因为我想的lib代码是确定我得到的印象是你的问题更关系到构建过程：

我会试试下面的办法来furhter查明probem：

1. 使用重优化有时会导致以解决问题，在极少数情况下，默认优化也可能会发生删除所有优化。

2. 如果使用其他编译器构建boost作为可能导致问题的代码。如果你没有用相同的编译器自己编译，请尝试它。可能它甚至不会建立。

3. 使用第一个编译器修订版本（4.0.0,3.0.0 etc ..）也可能是一个问题，因为它们大多是bug（至少在GNU cc的情况下）。尝试4.1或其他。
