I write firmware where the program has to run for years unattended.

You are right, C with manual memory management, no lifetime management, lack of phat pointers and a culture of leet has problems with deranged maddening bugs that other languages don't have.

But this bug first shows how inband signaling is bad news usually. But worse it's a failure to adhere to the spec properly. If you implement a library and you don't adhere to the spec you're going to bone someone.

Perhaps even worse is obviously the spec doesn't come with any standard testing framework. That was also the root of Apples infamous goto bug.
