Re: Exception is not caught in RELEASE mode

Working with Visual C++ 6.0 (SP6).

I want to throw an exception from somewhere in a third party DLL.
Goes like this:

class CMyDocument : public CDocument
{
 ...
 void MyFunction();
 static void AFX_CDECL ReportError(BOOL bAbort, const char*
pszFormat, ...);
}

void CMyDocument::MyFunction()
{
 TRY
 {
   // calling some DLL code here
   // from the DLL the static CZoneCorrDoc::ReportError
   // will be called (by a function pointer), which throws an
exception
 }
 CATCH(CUserException, e)
 {
   // Note: DELETE_EXCEPTION_(e) not required
   AfxMessageBox("Exception caught");
 }
 END_CATCH
}

void AFX_CDECL CZoneCorrDoc::ReportError(BOOL bAbort, const char*
pszFormat, ...)
{
 ...
 if (bAbort)
 {
   AfxMessageBox("Throwing exception");
   AfxThrowUserException();
 }
}

It works as expected in DEBUG mode, however in RELEASE mode
the exception is thrown, but not caught in the CATCH block.

If I place a simple AfxThrowUserException call in the TRY block
it is caught in both DEBUG/RELEASE mode.

I am not very familiar with exceptions. Can anybody give me a
hint what might be the reason for this apparently strange behaviour.
