SYMPTOMS
When creating a temporary object and then re-throwing an exception, as demonstrated in the sample code in the More Information section of this article, the application terminates abnormally.



RESOLUTION
See the More Information section for the sample code and the workaround.



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ version 5.0.



Sample Code
/* Compile options needed: /GX /O2 */   class aClass {  public: aClass(const char*){} ; ~aClass{} ; } ;

void push(const aClass& val) {  }

void main {

int a = 5 ; try {        try {           throw a ; }        catch(int) {           //Workaround: uncomment the following 2 lines //aClass aObj("ABC") ; //push(aObj) ; //Comment the line below push("ABC") ; throw ; }        catch(...) {        }      }      catch(...) {     }   }
