    Similarly, the printf for outputting a backspace/erase sequence would also
    trigger a panic.
    
    This workaround (of not mixing fflush() with printf) is likely merely hiding
    a deeper issue, but it appears to be consistent. Plus, printf with no args

    * Work around IDF inconsistency with stdout buffering.
    
    * Increase console task stack size.
