Throwing exception inside exception handler will cause infinite loop (thanks Roman Puls for the report)

The following snippet:

void test() 
{
    int id = 101;
    PJ_USE_EXCEPTION;
 
    PJ_TRY {
        PJ_LOG(3, ("", "throwing signal %d now", id));
        PJ_THROW(id);
    } PJ_CATCH_ANY {
        id = PJ_GET_EXCEPTION();
        PJ_LOG(3, ("", "caught and reraising %d", id));
        PJ_THROW(id);
    } PJ_END;
 
    PJ_LOG(3, ("", "Never gets called"));
};

leads to an endless loop:

INFO: 08:58:50.682          throwing signal 101 now
INFO: 08:58:50.682          caught and reraising 101
INFO: 08:58:50.682          caught and reraising 101
INFO: 08:58:50.682          caught and reraising 101
...

Fixed in r2878:

• exception handler is now popped from the stack immediately in PJ_THROW
