This question provides more clarity on the problem described here. I did some more investigation and found that the stack unwinding is not happening in the following piece of code:

class One { public:     int x ; };  class Wrapper { public:     Wrapper(CString csText):mcsText(csText)     {         CString csTempText;         csTempText.Format('Wrapper constructor :: %s\n', mcsText);         OutputDebugString(csTempText);     }      ~Wrapper()     {         CString csTempText;         csTempText.Format('Wrapper destructor :: %s\n', mcsText);         OutputDebugString(csTempText);     }     CString mcsText; }; class Test {     public:      void notifyError()     {         try         {             int x = 10;          }         catch(...)  {}     }      void OnRecvBuffer()     {         try         {             Wrapper a('AddRef');                 One* p = NULL;             p->x = 10;         }         catch(...)         {             notifyError();         }        }    };    int main()  {     Test* pTest = new Test;      pTest->OnRecvBuffer();      OutputDebugString('Test'); }

I compiled this code using VC6 SP5 compiler and the output is ‘Wrapper constructor :: AddRef!!!’ (i.e. the destructor of wrapper object which was constructed on stack is not called. Is this the expected behavior ? or is it a bug with VC compiler ? Can I use some compiler flags so that the stack unwinding happens in this case?

  1. If you want to use SEH, you must use _set_se_translator function and /EHa compiler option.
