正则表达式在调试和发布版本上的行为不同

Question

boost::regex re("^\\s*([_\\w\\.]+)\\s*=\\s*([^\\s]+)$");
if(re.empty()){
  std::cout<<"How is this possible?"<<std::endl;
}

这行代码打印在我的发布版本中！(调试版本很好)使用MSVC 2008 (vc 9.0)

我转而使用visual studio 2005，这个问题消失了，但现在我在应用程序接近尾声时遇到了一个异常：

myApp.exe: 0xC0000005中0x0042d935处的未处理异常:访问冲突读取位置0xe06d7390。

调用堆栈是

kernel32.dll!7c812afb()

下面的帧可能不正确和/或丢失，没有为kernel32.dll加载符号

kernel32.dll!7c812afb()
