I'm using Debian's gcc 10.2.1.

Some kind of variable corruption due to a misconfiguration seemed like the 
cause when I encountered this problem.

Not immediately.

At some point, I will review the UART driver and also consider the MMC/SD 
driver as well. I've been looking at the latter functionality independently 
from Linux, so I might be slightly more productive when I am able to turn my 
attention to it.
