Fixing a uname bug (Apache NuttX RTOS)

I had recently run into an embedded problem where when switching the order of two functions in the source code, one of them would refuse to work. I tried a number of things without identifying the real error, and finally had to add a comment warning any later parties not to do this. I even checked the assembly and they seem to be consistent. But when I upload to firmware, the error keeps coming back over and over again.

There are a number of edge cases in embedded where static variables can become unreliable. I am not saying it is common exactly but it is certainly not unheard of. I usually keep it in my list of things to check when stuff is mysteriously going wrong

Bugs like these are fun to read about, but never fun to debug if you need to get something else done. Nice writeup by Lup Yuen Lee once again.

I like his work on the pinephone

... what was the bug?
