CSpsAppThread g_clsSpsApp;

Define g_clsSpsApp object, created two CSpsAppThread type of object, through CSpsAppThread (1) constructed object, procedure not end destructor will, but the layers of destructor, modify the string strNumber members, core, the call stack is as follows:


GDB debugging when p g_clsSpsApp. M_stQryCond strNumber, is an illegal address, but p g_clsSpsApp. M_stQryCond. StrNumber. C_str (), is an empty value ", "

Please help to look at the great god, the destructor string member is what will be the core?
