When I was debug, used QNetworkInterface::allAddresses() ，the application output will show :Invalid parameter passed to C runtime function.

Hi and welcome to devnet,

Please give your thread a meaningful title and give the details where you put the images.

Additional details like Qt version and OS would be good too.

I don't think it has anything to do with QNetworkInface but with debug in general.
I have the same output.
