It is even possible to rely on the default handler which invokes the 
debugger. You simply throw the exception from the se_handler.

void se_trans(unsigned int i, _EXCEPTION_POINTERS *p)
{
     throw;
}

Call

#pragma warning(disable:4535)
     _set_se_translator(se_trans);
#pragma warning(default:4535)

in main(). The pragma disable the warning that the application has to be 
compiled with asynchronous exception model. But this is irrelevant if 
you just rethrow the exception and the default handler terminates the 
application anyway.
