@@"

C++11 會造成 103 行的錯誤... 沒錯我也是用 C++11 XD ...

好新的BUG 12天前~


##########

目前正在安裝 1.51 版...

看起來 1.51 修正了很多 c++11  的問題.

http://www.boost.org/users/history/version_1_51_0.html

New Libraries

    Context: Context switching library, from Oliver Kowalke.

Updated Libraries

    Algorithm:
        Fixed is_sorted_until ; now matches the c++11 standard behavior on ranges with duplicate values.
        Added range support for the rest of the search algorithms.
        unhex now uses Boost.Exception to signal bad input.
    Asio:
        Fixed an incompatibility between ip::tcp::iostream and C++11 (#7162).
        Decorated GCC attribute names with underscores to prevent interaction with user-defined macros (#6415).
        Added missing #include <cctype>, needed for some versions of MinGW.
        Changed to use gcc's atomic builtins on ARM CPUs, when available (#7140).
        Changed strand destruction to be a no-op, to allow strand objects to be destroyed after their associated io_service has been destroyed.
        Added support for some newer versions of glibc which provide the epoll_create1() function but always fail with ENOSYS (#7012).
        Changed the SSL implementation to throw an exception if SSL engine initialisation fails (#6303).
        Fixed another regression in buffered_write_stream (#6310).
        Implemented various minor performance improvements, primarily targeted at Linux x86 and x86-64 platforms.
    Config:
        Deprecated a whole bunch of macros that were c++11 specific, but not named to show that they were c++11 specific. Made new macros with better names, and paired the old macros with the new ones. Updated the documentation to list the deprecated macros.
    Chrono:
        #6918 Boost Chrono compilation failure on HP uX due to undefined pthread_getcpuclockid.
        #6241 boost::chrono compilation problems without std::wstring support.
        #6987 Documentation & C++11.
        #7041 time_point.hpp depends on Boost.System.
        #7042 Avoiding time_point and duration dependency on time.h and CLOCK_REALTIME.
        #7058 Make it work when BOOST_NO_EXCEPTIONS is defined.
        #7069 Misspellings in clock_string<thread_clock>.
        #7081 WinError.h capitalization in boost/detail/win/basic_types.hpp.
    Geometry:
        points accessed through a pointer (e.g. in a linestring) should now be specialized without the pointer. In previous versions a type my_point used like linestring<my_point*> had to be specalized like: template<> struct tag<my_point*>. Now the library itself removes the pointer before calling the traits class, so now it should be like: template<> struct tag<my_point>
        intersection was sometimes wrong for integer points, fixed
        documentation, order of parameters in simplify was wrong, fixed
        7030 spherical distance, fixed (by patch of Karsten Ahnert)
    Graph:
        Refactored support for internal and bundled properties in Boost.Graph-provided graph types, and cleaned up named parameter functionality:
            Enabled old-style (non-bundled) internal properties in compressed_sparse_row_graph.
            Bundled properties should work correctly for all graph types and adaptors.
        Bugs fixed:
            #6993: Typo Bundled Properties document
            #7002: Problem with initialization of CSR bidirectional graph
            #7023: Enclose internal type graphml_reader in anonymous namespace
            Other bugs and warnings not in Trac
    Hash:
        Support the standard smart pointers.
        hash_value now implemented using SFINAE to avoid implicit casts to built in types when calling it.
        Updated to use the new config macros.
    Lexical cast:
        Better performance, less memory usage for boost::array<character_type, N> and std::array<character_type, N> conversions.
        Fixed bug with volatile input parameter #7157.
    Math:
        Updated to use the new config macros.
    MSM:
        Support for boost::any http://www.boost.org/doc/libs/1_51_0/libs/msm/doc/HTML/ch03s03.html#any-event or kleene http://www.boost.org/doc/libs/1_51_0/libs/msm/doc/HTML/ch03s04.html#kleene-event as acceptable events
        Bugfix: compiler error with fsm internal table and none (compound) event.
        Bugfix: euml::defer_ leading to stack overflow.
    Proto:
        Proto transforms get pseudo-parameter pack expansion support for unpacking expressions. See the Release Notes for more information.
    Ratio:
        #7075 Workaround for error: the type of partial specialization template parameter constant "n1" depends on another template parameter.
    Regex:
        Updated to use the new config macros.
    Thread:
        #4258 Linking with boost thread does not work on mingw/gcc 4.5.
        #4885 Access violation in set_tss_data at process exit due to invalid assumption about TlsAlloc.
        #6931 mutex waits forwever with Intel Compiler and /debug:parallel
        #7044 boost 1.50.0 header missing.
        #7052 Thread: BOOST_THREAD_PROVIDES_DEPRECATED_FEATURES_SINCE_V3_0_0 only masks thread::operator==, thread::operator!= forward declarations, not definitions.
        #7066 An attempt to fix current_thread_tls_key static initialization order.
        #7074 Multiply defined symbol boost::allocator_arg.
        #7078 Trivial 64-bit warning fix on Windows for thread attribute stack size
        #7089 BOOST_THREAD_WAIT_BUG limits functionality without solving anything
    Unordered:
        Fix construction/destruction issue when using a C++11 compiler with a C++03 allocator (#7100).
        Remove a try..catch to support compiling without exceptions.
        Adjust SFINAE use to try to supprt g++ 3.4 (#7175).
        Updated to use the new config macros.
    Wave:
        See the Changelog for details.
    xpressive:
        Work around buggy wide ctype facet on cygwin and mingw.
        Work around absence of __isctype on some glibc implementations.
        op::as shouldn't assume string::iterator != char*.
        Fix assertion in cpp_regex_traits on libc++, thanks to John Fletcher.

0x2abe54002e90 是被我丟到 map 裡的 指標.

拿它出來用 並且 close socket 不會有問題...

但是 寫程式 跑了 幾十分後才會出現這個問題.....

哈~把測試程式打進去~~跑了很久~都不會了~果然解決了~~

C++11 << 造成 1.50 版本不相容.

用太新的技術也中槍~~~~@@

@@"

全部重新編譯後....

並且重新載入 ldconfig .

又完全不會了~~給它壓測一晚看看吧~XD....

是怎樣~

XD 一定要休息了....

有可能是我自己在異步IO下長指標造成的錯亂.

晚一點利用 BOOST 內建的智慧型指標 shared_ptr 再來玩一次看看.

解決了...

我是硬解的 目前還不知道為什麼指標丟到 close  內 .

impl 為什麼會 Segmentation fault.

於是我 把 指標 socket 的狀態一個個倒出來看.


        std::map<int,tcp::socket*> usock;
        std::map<int,tcp::socket*>::iterator usockit;
        std::pair<map<int,tcp::socket*>::iterator,bool> socketRet ;
        tcp::socket* psocket ;

        boost::system::error_code ec;
        boost::asio::ip::tcp::socket::keep_alive option;

        psocket = getUsock(uid) ;
        psocket->get_option(option, ec)  ;   <<< 這裡每次在還沒有出現 Segmentation fault. 時會倒出 0
                                                                         但是一但出錯就會倒出 9 , 88
                                                                         於是我把 倒出來是 9 , 88 以外的動作停下來 讓 0 的動作發生.
                                                                         有空再查 system:9 , system:88 是什麼意思.


這個問題有可能是重覆 FREE 記憶體造成的.

等我找到 system:9 代表什麼意思就有解答了.
