ESP-IDF V5.2.3 Bug or Miss Interpret in Compiler at Printf level (IDFGH-13927)

[filzek]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

There is an error inside the Printf compiler optmizations and also with the stub.

unsigned long sensor_received = 12345647;
unsigned long last_sensorid_received = 12345649;
unsigned long sensor_length = 0;
struct timeval tv2;
gettimeofday( & tv2, NULL);
printf("Time: %ld seconds\n", tv2.tv_sec); // Separate print for tv.tv_sec

	printf("Before first printf: sensor_received = [%lu]\n", sensor_received);
	printf("RECEIVED [%lu]\n", sensor_received);
	printf("Before second printf: sensor_received = [%lu]\n", sensor_received);

	printf("[%d] [%ld] RX433 Received: SENSOR [%lu] - last_sensorid_received [%lu]\n",
   __LINE__, tv2.tv_sec, sensor_received, last_sensorid_received);

	printf("[%d] RX433 Received: SENSOR [%lu] - last_sensorid_received [%lu]\n",
				 __LINE__, sensor_received, last_sensorid_received);

	printf("RX433 Received: SENSOR [%lu] - last_sensorid_received [%lu]\n",
				 sensor_received, last_sensorid_received);

to validate all kind of possible acttions the code try all kinds.

Before first printf: sensor_received = [12345647]
RECEIVED [12345647]
Before second printf: sensor_received = [12345647]
[1526] [0] RX433 Received: SENSOR [0] - last_sensorid_received [12345647]
[1529] RX433 Received: SENSOR [12345647] - last_sensorid_received [12345649]
RX433 Received: SENSOR [12345647] - last_sensorid_received [12345649]

1526] [0] RX433 Received: SENSOR [0] - last_sensorid_received [12345647]

this could be related to the %ld type not being correct alligned with the compiler in this arguments?

as of using
printf("[%d] [%" PRId64 "] RX433 Received: SENSOR [%lu] - last_sensorid_received [%lu]\n",
LINE, tv2.tv_sec, sensor_received, last_sensorid_received);

this prints correct, so, why in the esp-idf the type is PRId64 ?
