Exception in delete operator

[Olivier DERVYN]

Exception is not rethrow form overloaded delete operator

 

Her e a short form of my code :

 

void operator delete( void * ptrMemory ) throw()
{ 
    try
    {
        if( mg_nStatus )
        {
           BlockFree( ptrMemory );
           mg_nStatus--;
        }
        else
           BlockFree( ptrMemory ); 
     }
     catch( MemoryException * e )
     {
         throw e;
     }
}

 

bool MG_MisMatchAlloc1()
{
    char *      buf1 = new char[5];

 

    // use delete in place of delete[]
    try
    {
        delete buf1;
    }
    catch( MemoryException * e )
    {
        delete e;
        delete [] buf1;
        return true;
    }
    catch( ... )
    {
        delete [] buf1;
        return true;
    }

 

    return false;
}

 

 

MG_MisMatchAlloc1() call "delete buf1" in place of "delete [] buf1" my operator delete

is called, then BlockFree (my memory handler) is called too.

BlockFree generate an exception, exception is caught in operator delete but not rethrow.

Default exception handler is called instead of my catch section (for test reason, I have added a catch all section).

 

Please, anybody can confirm this problem and send me a workaround.

 

Regards, Olivier
