ESP32 Forum

I am using the ESP32 port of Azure SDK. I noticed this issue mentioned in several places for many months but it has never been put into the master branch.

In file azure-iot-sdk-c/iothub_client/src/iothubtransport_mqtt_common.c
a local variable on line 1496 size_t request_id;
is not initialized.

When building in Release configuration, the compiler treats as a fatal error on line 1518.

azure-iot-sdk-c/iothub_client/src/iothubtransport_mqtt_common.c:1518:32:
error: 'request_id' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Yes, I can edit this myself to set to 0, but I try to treat the Azure library as untouchable 3rd party code.

Can someone please check in the fix to the master branch?

Thanks!

Since that code is part of an external codebase, we cannot change it as of now. However, we have aded a fix to suppress that error. Going ahead, when we move to a newer azure-iot-sdk-c , we will ensure that the error is fixed in the actual source itself.
