C++ 为什么从DLL调用boost:：wave:：context构造函数时会死锁？,c++,boost,dll,C++,Boost,Dll,我有一个名为PreProcessSource的函数，它分配boost:：wave:：context并进行一些预处理；一点也不奇怪 std::string PreProcessSource(const std::string& instring, const std::string& defines) { typedef boost::wave::cpplexer::lex_token<> token_type; typedef boost::wave:

我有一个名为PreProcessSource的函数，它分配boost:：wave:：context并进行一些预处理；一点也不奇怪

std::string PreProcessSource(const std::string& instring, const std::string& defines)
{
    typedef boost::wave::cpplexer::lex_token<> token_type;
    typedef boost::wave::cpplexer::lex_iterator<token_type> lex_iterator_type;
    typedef boost::wave::context<std::string::iterator, lex_iterator_type> context_type;

    std::string source = instring;
    context_type ctx(source.begin(), source.end()); // DEADLOCK here
    ctx.set_language(boost::wave::enable_emit_line_directives(ctx.get_language(), true));

    if(!defines.empty())
    {
        std::vector<std::string> tokens;
        Split<std::string>(defines, tokens, ",");

        std::vector<std::string>::const_iterator cit = tokens.begin();

        for (;cit != tokens.end(); ++cit)
            ctx.add_macro_definition(*cit);
    }

    context_type::iterator_type first = ctx.begin();
    context_type::iterator_type last = ctx.end();

    std::string outstring;

    while (first != last)
    {
        const token_type::string_type& value = (*first).get_value();
        std::copy(value.begin(), value.end(), std::back_inserter(outstring));
        ++first;
    }

    return outstring;
}
代码针对x64编译，并处于调试模式。 我使用以下选项将boost编译成DLL（使用bcp获取我使用的库的文件）：

预处理器：

  • WIN32
  • 增强所有的无库
  • 增强所有动态链接
  • BOOST\u线程\u构建\u DLL
  • _动态链接库
  • _调试
  • _窗户
  • _USRDLL
代码生成：

  • C++异常（/EHsc）
  • 多线程调试DLL（/MDd）
  • 功能级链接（/Gy）
  • 数据流单指令多数据扩展指令集2（/arch:SSE2）（/arch:SSE2）
  • 快速浮点模型（/fp:Fast）
DLL A使用相同的选项，除了BOOST\u ALL\u DYN\u LINK、BOOST\u THREAD\u BUILD\u DLL和字符串池选项

Boost单元测试库作为静态库单独构建

以下是工作版本的堆栈跟踪：

Nitro.dll！Boost：：Call一次（Booo:：OncIh旗和旗，Vale+Valf）200行C++
Nitro.dll！Boost：（空虚（空）*FUNC，Booo:：OncIh旗和旗）28线C++

Nitro.dll！boost:：spirit:：classic:：static\up>我发现boost的trac上打开了以下票据：

它说call_once不是可重入的，不应该递归调用。因此，我使用的代码是未定义的行为；这张票被标上了“无法修复”的字样

我采取的解决方案是创建一个单独的DLL，它只包含预处理源函数
