| // This program, when compiled with AVR-GCC 7.3.0, the standard version | |
| // for the Arduino AVR framework, will generate wrong debugging information. | |
| // When stopped just before the line buf[0] = ... and setting | |
| // num to 1001, then after two single-steps, num has become 1003 (which | |
| // is not true!), and after another singel-step it is back to 16000. | |
| // You can check that, e.g., by using simavr and avr-gdb. | |
